passing header information on to backend Apache/PHP

[Peter Langhans]

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
