Dusty pages not accessable from apache server

 2:08 pm on Feb 26, 2013 (gmt 0)

We are using apache 2.2.3 on Red Hat Enterprise Linux Server release 5.8 Beta (Tikanga).

We have many virtual hosts setup in single apache server.When the backend application server is down, we configured dusty pages in virtual host files, but these arent accessable via browser.Checked everything i could but couldnt find anything.


virtual host: example.com
DocumentRoot: /home/atgwww/docroot/
Dusty page : /Dusty/store/GFdusty.html

$ pwd
$ ls -lrt GFd*
-rwxrwxr-x 1 atgwww atgwww 499 Apr 20 2012 GFdusty.html

Hi phranque,
When i hit the url its redirecting me to application configured in virtual host i.e backend war file deployed on weblogic. But when i try to hit the dusty page directly i get the apache failure error as shown above.

My vhost file:

this looks like it could be suspect:

<IfDefine !usty>

even more likely, i don't immediately see how this LocationMatch would trigger for a /Dusty path:

<LocationMatch "^/(ancillary-access|certs|MEDIA_*|static|ProductImages|CategoryImages|Utilities_Web|Images|logview)">

in either case if apache doesn't process the WebLogicCluster directive that probably is the cause for the missing server host parameter.

Incase the WebLogicCluster defined is down, it should show the custom error page as mentioned in the apache plugin paramters link.


Even though weblogic isnt down, when i hit the url
example.com/Dusty/store/GFdusty.html it should show the dusty html file. This setup is working in one environment and not in another.
