Hello,

we're experiencing a strange problem with apache. I know this at the
first glance looks almost like "FAQ", but it isn't, we've spend days
looking through all docu, FAQ's, googled groups and the web... to no
avail.

We've successfully setup the server to listen both on 80 and an SSL
version on 443. At some time later we will have some pages served via
80 (non-secure) and some pages only after certificate based
authentication via SSL. At the moment everything works both on
http://... and https://...

We first had everything working via normal prot 80. Then we configured
SSL and set up a VirtualHost for that. So far so fine. Everything
seemed to work, including the certificate based authentication.

However if any of the Web-pages issues a "redirect" on the secure
server side, e.g. after a login on
https://host.sub.domain.com/umufasel/login.jsp, the web-browser is
redirected to http://host.sub.domain.com:443/umufasel/index.jsp
instead of https://host.sub.domain.com/umufasel/index.jsp
This of course then fails as the browser tries to speak http while on
443 https is waiting and SSL can't decrypt.

It can't be obvious stuff like missing "-D SSL" when starting apache
or missing certificate. Not tripple, but 100 times checked. https
protocol really works. It's just the redirect that somehow generates a
wrong URL and sends it to the brower.
Also be assured, that the JSP pages where this happens DO use relative
URL. They do not specify the crappy URL hardcoded.
(e.g.: response.sendRedirect(response.encodeRedirectURL(" ../index.jsp")
)

I've already browsed/search both on apache and the rest of the web
with google. However I've not been able to solve the problem. All the
hints I get describing exactly this problem are related to
Tomcat/Jakarta. Well, I followed their hints, but most of the Tomcat
cases are relevant when using Tomcat standalone, but in our case we
use Tomcat via Apache, so those solution do not apply.

I have no clue where the new, redirected, URL is generated and how it
can get so strangely wrong. I've but debugging in Tomcat and apache on
debug, but I can't find a clue in the logfile.

We thought of workaround using redirect or rewrite. Unfortunately
rewrite doesn't help, as the browser tries to speak HTTP to the server
via port 443, but the SSL handshake fails of course on such a low
level, that apache does not even get the request, so that rewrite does
not fire.

Any ideas? I stripped the comment from httpd.conf and ssl.conf (which
is included by httpd.conf) and included both below. I also included
mod_jk.conf, which is also included by httpd.conf.

What did we overlook? We're lost!

Thanks in advance for any hint!

Herbert
