[LoadUIWeb] Regular expression for data selector

Hi, I need to use a data selector for a dynamic ID in a response to use in subsequent requests. The reponse looks like this:



request=request1&rid=R67gft*6453GBH"



So I have created a data selector with the name of "rid", subexpression "$1" and with the following regex: 



rid=(.*?)\"



And in the follwing requests I use it as follow:



rid=@rid@



Is this correct? Is the regex not including the "rid=" part, which leads to a request of:



rid=rid=R67gft*6453GBH"



instead of the wanted:



rid=R67gft*6453GBH



Just want to make sure I make the correct regex here.
