Nimbostratusirule to allow only certain uris
I'm trying to create an simple iRule that will allow only uris that are in the data group "allowed uris". My iRule is:
when HTTP_REQUEST {
if {[matchclass [HTTP::uri] equals "allowed_uris "]}
{forward}
else
{discard}
}
and the data group is defined as:
class allowed_uris {
"/site1/*"
"/site2/*"
"/site3/*"
}
When the iRule is enabled, it seems to discard all http requests. Is my data group syntax wrong or is there something wrong that I'm not seeing in our iRule?

This should work, note Data Groups interpret * literally, you can't use wildcards, remove these before trying this;when HTTP_REQUEST { if { [ class match [string tolower [HTTP::uri]] contains allowed_uris ] } { Stop processing the iRule for this event here return else { drop } } }- What_Lies_Bene1
Try these, found in a post by Hoolio; http://www.zytrax.com/tech/web/mobile_ids.html http://en.wikipedia.org/wiki/List_of_user_agents_for_mobile_phones
scarnes_82101Thanks,
When I try the iRule above, I'm getting:
01070151:3: Rule [allowed_uris] error: line 4: [wrong args] [return else { drop }]
Any thoughts?- What_Lies_Bene1Sorry, a bracket was in the wrong place;
when HTTP_REQUEST { if { [ class match [string tolower [HTTP::uri]] contains allowed_uris ] } { Stop processing the iRule for this event here return } else { drop } } - scarnes_82101Removing the * from the data group and using the updated iRule works like a charm. Thanks for the assist.
- What_Lies_Bene1You've very welcome.

One additional note here, be sure to enter the uri strings in the data group all lowercase when using the string tolower cmd in your irule.
