Larry,

thanks for your reply again. Sorry I stole your time for my own dumbness.

It's totally possible to do it via headers. The example I gave above, works
perfectly. I have just been too dump to test it in https (I tested in http)
and wondered why the header does not come through as expected :( Oh lord.

So just for reference. As the manual states correctly, you can pass any
header information on to your backend scripts via the

proxy_set_header Header-Name Header-Vale;

directive. Apache does NOT filter it out, and it's visible within PHP by
using one of the two following options:

1.) use the normal $_SESSION variable. CAVEAT: when using the $_SESSION
variable your header "Header-Name" becomes "HTTP_HEADER_NAME" (watch casing
and underscore instead of dash)

2.) use the apache_request_headers function to retrieve original/unchanged
values (http://uk.php.net/apache_request_headers)

Thanks for your time, folks!

Pete
