Symptoms

1.  There is a portal registered on a server called abc.com (which is only accessible via the Intranet).
2.  This server has many virtual hosts also, so Portal can be accessed via the following URLs (which are public):

http://abc1.com/pls/portal
http://abc2.com/pls/portal
http://abc3.com/pls/portal
http://abc4.com/pls/portal

[port 80 is the WebCache port]

3.  Trying to access Portal via the Intranet URL (http://abc.com/pls/portal), gives the following error:

Not Found
The requested URL /pls/portal was not found on this server.
Oracle-Application-Server-10g/9.0.4.3.0 Oracle-HTTP-Server Server at sso.com Port 443

4.  SSO is SSL-enabled on sso.com (and resides on the same box as abc.com but on another IP address) and is working.
5.  When accessing a virtual host, it correctly re-directs (after logon), to the Portal Builder homepage, i.e.

http://<virtual host>/portal/page?_pageid=6,1,6_13&_dad=portal&_schema=PORTAL

6.  Every time the http://abc.com/pls/portal page is requested, the Infrastructure error_log file has the following message:

[error] [client xxx.xx.x.xxx] [ecid:
xxxxxxxxx:xxx.xx.xx.xxx:xxxxx:x:xxx,0] File does not exist:
/opt/oracle/product/as10g/infra2/Apache/Apache/htdocs/pls/portal
