Can you just remove it from the requested URI? If so, you can use an iRule like this: 


when HTTP_REQUEST {

 Check if the path contains a jsessionid
if {[HTTP::path] contains ";jsessionid="}{

 Split the path on the jsession ID and update it to the first field
HTTP::path [getfield [HTTP::path] ";jsessionid=" 1]
}
}

Or if you need to hide the JSESSIONID from the client you'd need to rewrite the response content using an stream profile and STREAM::expression iRule. You could use a STREAM::expression like:

STREAM::expression {@;[jJ][sS][eE][sS][sS][iI][oO][nN][iI][dD]=[a-zA-Z0-9]*@@}
