Subject RE: [users@httpd] Rewrite and https
Date Thu, 04 Aug 2005 11:38:31 GMT
You learn stuff every day... Thanks for taking the time to fill in the gaps.

 WRT to the order in which rewrite rules are executed, you can add the following directive
to the VH:

RewriteOptions inherit

Then you can add the rewrite rules that should be executed after the rewrite rules in the
main server, below that.

-ascs

The problem is not only returning proper URLs but telling the weblogic server that a request
came in over https.

I am not the one that decides which java method will be used, and the powers that do decide
about this have allready decided that they whant the argument "protocol=https"  added... So
I have no option but to add it...

An extra problem I have is that I have about a hundred rewrite rules, and the order they are
porcessed in is important. I don't know how to add a rule to the  SSL virtual host, and maintain
the processing order I want. And I also don't want to maintain two complete sets of rules...

I have now found out why it wouldn't work though. This is a bug in the mod_rewrite shipped
with apache 2.0. It definitely exists in 2.0.50, but has aparently been fixed now. I'll upgrade
when possible. In the mean time the folowing workaround worked for me:

 # If Portal is accessed over https add a query parameter so the portal knows.
        RewriteCond     %{LA-U:ENV:HTTPS}        on
        RewriteRule ^/([Pp]ortal.*)     $1?protocol=https       [QSA]
