Using iRule to block a URL in Virtual server but doesn't work

it is working for me:

curl -v http://10.3.22.85/xyz

Jul 28 21:27:40 bigip-01 info tmm1[21016]: Rule /Common/irule-devcentral-test : dropped

what isn't for you?

Hi,

Do you have other irules attached to your Virtual Server ?

Can you check ltm logs in /var/log/ltm looking for TCL errors. Typical case is when you see this kind of log :

Operation not supported. Multiple redirect/respond invocations not allowed

Try this instead:

when HTTP_REQUEST { 
    if { [string tolower [HTTP::path]] starts_with "/xyz" } {
        log local0. "dropped" HTTP::respond 200 content "URL Blocked"
        reject
    }
}

.

[Edit: Added reject, just for your testing]

Do you really want a response back. Try closing the TCP connection & disabling all events after the response is send.

when HTTP_REQUEST { 
    if { ( [string tolower [HTTP::path]] contains "/xyz" ) } { 
            log local0. "dropped" 
            HTTP::respond 200 content "URL Blocked" Connection "Close" 
            TCP::close
            event disable all
        } 

}
