What about passing parameter to your PHP script using rewrite rule?

rewrite ^(.*)$ http:// <http://<url to backend server or IP:port>/> <url to backend server or IP:port>/login.php?proto=SSL

I might not be understanding your exact problem though.

Hi,

I'm using nginx 0.6.35, apache 2.0.63 and php 5.2.9.

My problem is, that I need my php scripts to know in some way or another whether SSL is used or not (to include either https or http javascript files e.g.).

When using nginx as webfrontend proxy, it accepts all the ssl connections and it's working fine, but when I proxy through to apache, the knowledge about SSL is 'lost'. If possible, I don't want to be using different ports for proxying through to apache.

I thought it'd be enough to set headers like:

for 80: proxy_set_header X-Secure of;

for 443: proxy_set_header X-Secure on;

put I have not found a way how I could retrieve those values from within the php script. They seem to be filtered out by Apache.

Does anyone have an idea how I can get any custom set header, set in the nginx.conf through to the php scripts?

Thanks a lot, Peter
