web_custom_request EXTRARES webresource.axd

[sqa]

my application is asp.net with ajax controls ,
I am using loadruner 8.1 , html recording mode

in my script the web_custom_request EXTRARES has

"Url=WebResource.axd?
d=BSw5a4DsQDnNh8f9BFtmgzvoQEm8z7MGK-1RN2_wetYlPS99PZkVPhT_cErh0eZbWw92CF51TsR0ZaerlPOa5ZGl75PDJk9q9ZBW-42mQEUozETj9LnRF92-
XVcZsV-L0&t=633265640513322230", "Referer=http://appfolder/
page1.aspx", ENDITEM,

what are these webresouce.axd values .

Does these values change if the test server changes ?

Do i need to correlate & prameterise those ?

>From where to capture these to pass in the next request ?

These are the session values and you need to correlate the following values

Change you recording section and make sure you are selecting the user action
type of recording.Please note that LR8.1 has very poor support of asp.net.

I would suggest you to upgrade to LR 9.0 if you are not good in LR.
