Problem in Notes Agent and Web service when accessed by multiple users

Guys

I am having an notes agent which hits the webservice and gets the reponse in xml.

I am storing that xml file along with the corresponding xslt file in a server’s local drive. After which I do transformation (xml + xslt = html) to show the results to the user in html page.

The problem here am facing is…

It is working fine as a single user interface. but when multiple user try accessing that agent. the xml and xslt file are overwitten. since I am creating only one xml and xslt file for the whole transaction.

Please help/ suggest if am going wrong.

Thanks in advance
