[HTTP::uri] rewrite fail,help please ,thanks

Hi Zongfeng,

Up until 11.0, the values for HTTP::path, HTTP::uri and other commands are cached within the same iRule event priority even if you modify them. The values are still changed for the request though. So what you're seeing is expected even though the URI has been updated. You can verify this by logging the values in a later HTTP_REQUEST event using priority:

when HTTP_REQUEST priority 501 {
   log local0. "Updated URI in 501: [HTTP::uri]"
}

Here is a list of at least some of the HTTP:: commands which are cached:

HTTP::password

HTTP::username

HTTP::host

HTTP::path

HTTP::query

HTTP::request_num

HTTP::status

HTTP::uri

HTTP::is_keepalive

HTTP::is_redirect

HTTP::request

Again this was fixed in 11.0 so the return values are updated when they're changed.
