[jilong yang]

thanks very much !!

I wan't to check the query string , and I can use vcl to work for it where
GET method.
I hope to check the POST string too ,how can I do ?
I find the post data follow the http header in sp->http0->ws ,  and the post
data in htc->rxbuf->b too .
can I do the check POST DATA work on HTC_Rx ?
