configure caddy behind proxy

[Franck17000]

Hi !

We're trying to upgrade our PLA to v2 dockerized version. We are using in front web, proxy servers who presents ssl certificates, all our websites behind communicate through proxys (internal) with http.

When webapp can autodetect it's url, it returns "http://" instead of "https://", then we add SetEnv HTTPS "on" into apache's virtualhost configuration file (eg. Wordpress, Simpltext...)

My docker's image PLA is dropped on a webserver behind our proxy, configured as a proxy too.

---> <443:HAPROXY HTTP:80> -----> [<80:VIRTUAL WEBSERVER:81HTTP>----><81:PLA CONTAINER>]

If I use PLA's docker image, I can't configure (I don't know how..) Caddy to "SetEn HTTP ON" like I do with Apache.

I installed PLA 2.3 on a deb12 image with "install from source code", with apache, it runs fine but I'd like to use ready to run image.

Thank you !

Are you intending to have 2 HTTP servers in front of the container? I cant help you with that.

I provide an example of implementing PLA behind a proxy in the wiki.

Hi, thank you for your answer.

I finally managed to force header adding "requestheader" in apache's host config file, it looks ok now :-)

<VirtualHost *:80>
    Protocols h2
    ServerName pla-test.mydomainIpreferHide.com
   SetEnv HTTPS "on"
   ProxyPass / http://10.20.30.40:81/
   ProxyPassReverse / http://10.20.30.40:81/
   SetEnv force-proxy-request-1.0 1
   SetEnv proxy-nokeepalive 1
   RequestHeader set X-Forwarded-Proto https
 </VirtualHost>
