How can I test web stress tool with pages use ajax updatepanel?



Hello Paessler team,

I downloaded your trial webstress test tool 7 and testing its features. We have got an intranet asp.net web application which is using ajax updatepanels in some cases to refresh the page content. However I recorded the communication post datas and urls it seems to me there is something wrong. Is it possible to test applications like mine with your web stress tool?

Thanks, Istvan

Although Webstress contains a URL recorder that does record most AJAX calls it is not designed to load test AJAX websites automatically.

In order to test your wen application you must create a URL script (or a set of URLs) that mimics the browser behaviour to the server as accurately as possible. This must be done manually.

I changed the program behaviour and now the software can be recorded the urls. In the logs I saw that there are a lot of image request which are bad. When I copy paste the link into a browser near the bad request error message i see that it is valid.


#2: IMAGE-Request 5: Time=9 ms, TFB=8 ms, Bytes=1 346, HTTP-StatusCode=400 (Bad Request) URL #1=http://localhost:1947/login/../Images/Login/login_main_pict.png Bad Request

Thank you for your information in advance.
