iRule - will this work?

Question

Sorry if this is a stupid question. 
I'm a novice trying to validate a iRule and looking for expertise kindness / help.
Just trying to logout &amp; re-direct if the its a second time visit to a uri pattern. Will the following work?&nbsp;

when HTTP_REQUEST {
if { [HTTP::uri] contains "xyz.com"}{
expr { [mcget {session.custom.logpatterncount}]+1}&nbsp;
if {expr { [mcget {session.custom. logpatterncount}] eq [2] }&nbsp;
{
                ACCESS::session remove
                log local0. "hit for logout button"
                HTTP::redirect "http://www.test.com"
   }
}
}&nbsp;

you cannot manipulate APM session variables directly in the iRule. You have to "import/export" them with command ACCESS::session data set/get&nbsp;
check: sol13296: Changing the value of an access policy session variable using an iRule&nbsp;
ACCESS::session&nbsp;

Thank you ! Something like below?
when HTTP_REQUEST {
if { [HTTP::uri] contains "xyz.com"}
{
ACCESS::session data set session.temp.logpatterncount [+1]
if {ACCESS::session data get session.temp.logpatterncount eq [2] }
{
            ACCESS::session remove

log local0. "hit for logout button"

HTTP::redirect "http://www.test.com"

}
}
}
