-There are 3 operating modes (CrowdsecMode) for this plugin:
+Appsec feature is supported from plugin version 1.2.0 and Crowdsec 1.6.0.
+
+The AppSec Component offers:
+
+- Low-effort virtual patching capabilities.
+- Support for your legacy ModSecurity rules.
+- Combining classic WAF benefits with advanced CrowdSec features for otherwise difficult advanced behavior detection.
+More information on appsec in the [Crowdsec Documentation](https://doc.crowdsec.net/docs/next/appsec/intro/).

+
+There are 4 operating modes (CrowdsecMode) for this plugin:
 
 | Mode | Description |
 |------|------|
 | none | If the client IP is on ban list, it will get a http code 403 response. Otherwise, request will continue as usual. All request call the Crowdsec LAPI |
 | live | If the client IP is on ban list, it will get a http code 403 response. Otherwise, request will continue as usual.    The bouncer can leverage use of a local cache in order to reduce the number of requests made to the Crowdsec LAPI. It will keep in cache the status for  each IP that makes queries. |
 | stream | Stream Streaming mode allows you to keep in the local cache only the Banned IPs, every requests that does not hit the cache is authorized. Every minute, the cache is updated with news from the Crowdsec LAPI. |
+| alone | Standalone mode, similar to the streaming mode but the blacklisted IPs are fetched on the CAPI. Every 2 hours, the cache is updated with news from the Crowdsec CAPI. It does not include any locally banned IP, but can work without a crowdsec service. |
+| appsec | Disable Crowdsec IP checking but apply Crowdsec Appsec checking. This mode is intended to be used when Crowdsec IP checking is applied at the Firewall Level. |
 
-The streaming mode is recommended for performance, decisions are updated every 60 sec by default and that's the only communication between traefik and crowdsec. Every request that happens hits the cache for quick decisions.

 We come from a web development and security engineer background and wanted to add the power of a very promising technology (Crowdsec) to the edge router we love.

+We initially ran into this project: [github.com/fbonalair/traefik-crowdsec-bouncer](https://github.com/fbonalair/traefik-crowdsec-bouncer)
 It was using traefik and forward auth middleware to verify every request.  
 They had to go through a webserver which then contacts another webservice (the crowdsec LAPI) to make a decision based on the source IP.  
 We initially proposed some improvements by implementing a streaming mode and a local cache.

+# Example
+## Enabling AppSec WAF feature from crowdsec
+
+You mostly need to configure Crowdsec for this to work by enabling virtual patching and configuring some custom rules.
+In the example we use a whoami container protected by crowdsec with virtual patching enabled.
+
+The Traefik instance just needs to know where appsec engine is located
+```yaml
+  labels:
+      
+      - "traefik.http.middlewares.crowdsec-bar.plugin.bouncer.crowdsecappsecenabled=true"
+      - "traefik.http.middlewares.crowdsec-bar.plugin.bouncer.crowdsecappsechost=crowdsec:7422"
+```
+We can try to query normally the whoami server:
+```bash
+curl http://localhost:8000/foo
+```
+
+And then we verify that a malicious request will be blocked: 
+```bash
+curl http://localhost:8000/foo/rpc2
+```
+You should get a 403 on http://localhost:8000/foo/rpc2
+
+To play the demo environment run:
+```bash
+make run_appsec
+```

+You can follow the documentation here: https://docs.crowdsec.net/docs/central_api/intro
+
+```bash
+curl -X POST "https://api.crowdsec.net/v2/watchers" -H  "accept: application/json" -H  "Content-Type: application/json" -d "{ \"password\": \"PASSWORD\",  \"machine_id\": \"LOGIN\"}"

+```yaml
+...

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+# simpleredis
+Minimal go redis with only `get`, `set` and `delete` operation.  
+It supports password authentication with redis.
+With **NO** external dependencies.
+
+## Example
+```go
+import simpleredis "github.com/maxlerebourg/simpleredis"
+
+var redis simpleredis.SimpleRedis
+
+redis.Init("redis:6379", "", "") // redisHost, redisPass, redisDatabase
+
+err := redis.Set("test", []bytes("whatever"), 60),  // Set key "test" with "whatever" for 60 seconds
+if err != nil {
+  ...
+}
+val, err := redis.Get("test") // get key test
+if err != nil {
+  // err could be only redis:unreachable, redis:miss or redis:timeout available in simpleredis.RedisUnreachable
+  ...
+}
+err = redis.Del("test")
+if err != nil {
+  ...
+}
+```
