I have a web application in which a user enters various information and also submits an RTF file. The file is then converted to a different format on the server and send back the result for the user to view. Can Webserver Stress Tool do a performance test on this? I tried to use the URL recorder, but it seems that it can only submit the form with application/x-www-form-urlencoded enctype while it should be multipart/form-data because there is a file upload control in the form. Is there anyway to change that to make it work? Thanks in advance for any help.
