proxypass irule

Hello,

 

I am trying to capture the 404 error from the www.myforumswebsite.com/myforum but I always get the remote 404 error page. If I go to www.abc.com/doesnotexist I get the custom 404 error which I have pasted below. If go to www.abc.com/forum/doesnotexist I get the error page from the www.myforumswebsite.com server. I want it to use the custom one I have below. How do I get the irule to capture the other 404?

 

 

 

 

 

---- code ----

 

when RULE_INIT {

 

set error_404 {

 

 

 

404 File or Page Not Found

 

 

 

 

 

 

 

 

[HTTP::status] Error

 

 

 

 

Page Not Found

 

The requested URL

$HTTP_URI

was not found on this server.

 

 

 

 

 

 

 

}

 

}

 

when HTTP_REQUEST {

 

set HTTP_URI [HTTP::uri]

 

}

 

when HTTP_RESPONSE {

 

if { [HTTP::status] == 404 } {

 

HTTP::respond 404 content [subst $::error_404]

 

}

 

}

 

--code ---

 

 

Thanks,
