Load testing ALM on the new functionality we deployed, but getting error as 403 Forbidden

Hi,

With the support of HP, we did some tweaks on the ALM application and now our client wants us to check the performance on the new functionality on ALM.

We are successfully able to record the ALM but while replaying the script we are getting 403 forbidden error, ofcourse this is the authentication error. But what is the proxy settings we need to give...

We have checked with web_set_user function, also while replaying with winInet....results in the same below error.. 

Error:

HTTP Status-Code=403 (Forbidden) for "http://alm11isr1srv:8080/qcbin/servlet/tdservlet/TDAPI_GeneralWebTreatment

System and LR details:

Win XP OS, LR 11.04 version, Protocol web (http/html)
