[users@httpd] Help with Virtual Hosting

[Neil Marjoram <n....@vam.ac.uk>]

I applogise if this subject has been posted before, I am a new member and have 
missed it!

I have a small problem with ScriptAlias and virtual hosts. I currently run 
Apache 1.3.6 on a Solaris system running a two vitual hosts, one of which is 
obsolete. These hosts were set up so that Apache could call the content 
management system using ProxyPass, and also some static pages we have 
installed outside the content manager.

I have recently installed a new system RH 7.3 with Apache 1.3.23 to replace 
the old Solaris system. Again two virtual hosts have been setup, one to call 
the old content management system and serve the old static site now installed 
on the new system, the other for a new site on the same system. 
Both these sites have their own cgi-bin and DocumentRoot. Everything works 
fine, except for ScriptAlias, the default ScriptAlias is set to /www/cgi-bin, 
which is the new cgi bin for the first site. This is also set in the virtual 
host section for the frst site, the second site is set within it's virtual 
host to /www/tm/cgi-bin. The second site works fine, but the first does not 
want to know, even when it is not specified in the virtual host section ( I 
would expect it then to take it from the server default). The only difference 
between the two v hosts is the use of ProxyPass. If I place a ProxyPass back 
to the localhost it works (as shown in extract) I have copied out the section 
in the httpd.conf file for the v hosts. Can anyone shed light on my problem - 
I guess I have scrambled the Proxy setup! Or perhaps this is how it is 
suppose to work ?

The cgi-directorys have ExecCGI set in the conf, the server listens on 
locahost:8081 and port 80 to allow the ProxyPass.
