[users@httpd] Help with apache reverse proxy (seg fault in error logs)
Hi
I have a simple requirement but nothing seems to work.
The details of a failed trial in given below.
Our web mail server is on "webmail.iitkgp.ac.in"
Webmail is accessible via
http://webmail.iitkgp.ac.in/webmail
In webmail.iitkgp.ac.in there is an internal url rewriting to
convert all "http" requests to /webmail/ to "https" requests
and that works.
** Now I would like all http[s]://www.iitkgp.ac.in/acMail/*
** urls to be proxied by www.iitkgp.ac.in to webmail.iitkgp.ac.in.
** as https://webmail.iitkgp.ac.in/webmail/*. How can I do that?
There are plenty of examples for http proxying and those
seem to work for me. But I am unable to proxy for https.
-----------------------------
# cat /etc/httpd/conf.d/110_local.conf
SSLProxyEngine on
<Location /acMail/ >
ProxyPass https://mx1.iitkgp.ac.in/webmail/
ProxyPassReverse https://mx1.iitkgp.ac.in/webmail/
</Location>
Url: http://localhost/acMail/
-----------------------------
Result on browser:
An error occurred while loading http://localhost/acMail/:
Connection to host localhost is broken

That is a moderately-old version of apache,and one that may have been
heavily modified by Mandrake. (They have a reputation in my books for
creating messed-up hacks based on apache, but I don't know anything
about that particular version.)

Time to get out your debugger:

Once apache has seg-faulted there is not much else you can do.
