Hi all,

I've installed Apache 2.2 and have an odd problem with accessing particular URL's within the portal. It seems to me that it should not be a problem but it may be related to the portal specifically.

What I would like is for someone to look at the way I have the ProxyPass and ProxyPassReverse statements defined to see if I'm missing something.

The portal runs on port 50000 and the HTML documents I display are using relative links for CSS and GIF files. It's these files that are not being retrieved but if I look at the properties of the GIF files, it appears to have a proper URL.

Example:

http://portal.domain/irj/portal is properly being redirected to http://portal.domain:50000/irj/portal.

The gif that will not display is:

http://portal.domain/irj/go/km/docs/documents/ADP/Static%20HTML/images/ADP-Outside-Plant.gif

But, if I add the port 50000 it does display.

Here are the Virtual Host settings I'm using

Code:
############################## For Reverse Proxy
ProxyRequests off
ProxyPreserveHost On

<VirtualHost *:80>

ServerName portal.domain

ErrorLog logs/portal.domain.com-error_log
CustomLog logs/portal.domain.com-access_log common

RewriteEngine On
RewriteLog logs/portal.domain_unsecured_rewrite.log
RewriteLogLevel 9

<Directory />
Options None
AllowOverride None
</Directory>


ProxyPass /irj    http://portal.domain:50000/irj/
ProxyPassReverse /irj http://portal.domain:50000/irj/

ProxyPass /webdynpro    http://portal.domain:50000/webdynpro/
ProxyPassReverse /webdynpro http://portal.domain:50000/webdynpro/
###################


Any ideas would be greatly appreciated.

Thanks,

Andrew

Try to put a trailing slash:

ProxyPass /irj/ ...
ProxyPassReverse /irj/ ...

ProxyPass /webdynpro/ ...
ProxyPassReverse /webdynpro/ ...

Not any rewrite rule somewhere that can cause it ?

You can try ProxyPreserveHost Off , who knows.
