Hi All ,

User have a requirement that if two host header are matched for ex. [abc.com](http://abc.com) and [cdf.com](http://cdf.com) with URI /poodle . Then Idle timeout should be set to 86400 seconds . Bu default it is 300 sec in tcp-lan-optimized profile .

I created a irule with help of irule/events in devcentral , please let me know if this will work logically :

when HTTP\_REQUEST {

if { (([HTTP::host] == “[abc.com](http://abc.com)”) or ([HTTP::host] == “[cdf.com](http://cdf.com)”)) and ([HTTP::uri] ==

“/poodle”) } {

IP::idle\_timeout 86400

set serverside\_idle\_timeout 1

} }

when SERVER\_CONNECTED {

if {$serverside\_idle\_timeout} {

IP::idle\_timeout 86400

}

}

Thanks

it looks okay to me.

by the way, i think it may be better to use “equals” instead of “==” for string comparison.

i understand this timeout is applied to traffic matching virtual server. one more thing i forgot. serverside\_idle\_timeout variable should also be initiated. otherwise, traffic that does not match if-condition in HTTP\_REQUEST will cause no such variable tcl error in SERVER\_CONNECTED.
