With "PHP checks" I meant that some pages (usually forms) check the URL the are called by and IF the URL begins with "http://" then automatically sends a "header('Location:');" (note the httpS). This is a 2nd security measure, as there is an Apache RewriteRule that executes firts and forces some directories to be only accessed by https.

That is the old model used in a web platform configured with ultramonkey (ldirector)

The new model has to change because as using Stunnel to decrypt the traffic on the balancer the httpS traffic never ever will pass the balancer and reach the web servers (in fact, none of these serves in :443). If I put the Apache RewriteRules and/or the PHP http-https redirections, I get an infinite loop because the connection always returns by HTTP to the web server.

This is the case of a web application maintained by us, but there are many other webs that we don´t want to touch code, like phpmyadmin, etc.

I think we need a equivalent reqirep or rspirep, possibly cobined with an ACL to make flexible rules in order to express the next logic:

if requests contains domain "" and url_path "/hireforms/" then replace "^http://" with "https://".

As you can see, I need to combine at least one and condition to check the domain plus the path because this new platform will host several domains and the http->https redirection has to be done only in some domain+path combinations.

Another aclaration, now I can access to: 1- 2-

The problem is that it must not to be possible to access by "1", but only by "2" and being automatically redirected to 2 if 1 was requested.

For all these things I said I think this is HAProxy's job to do this redirection.

I think it shouldn't be complicated but I spent some time playing with reqirep and rspirep and I didn't achieve the purpose.

Thank you very much for your help!! :)
