Hold request in wcf

i'm not sure if that is what u mean but in .net 3.5 you can get the client address/port/ip.

Get the Client’s Address in WCF

Hi,
acutally  i am getting the  request from different clients , i.e i am getting different threads

now i will send all these request to different application which is java , and they will place in their queue, and we don't know  for which request  the response comes from their queue because sometimes some queue may fails , so i need to check the for which request the response has come  by verifying with thread and send back the response to client, so here i need to sleep all the threads in WCF coming from client and after getting the response , i need to check for which thread i got the response and release that thread.

This is what my task, so can you please say whether i can achieve this by using mutex. if so, can mutex will  lock  multiple threads , please guide me how to achieve this.

The problem was solved
