Guest eswann Report post Posted June 2, 2009 Hello, when I try to perform load tests against my site, which is heavily ASP.Net AJAX, I get the following error: "The page is performing an async postback but the ScriptManager.SupportsPartialRendering property is set to false. Ensure that the property is set to true during an async postback." After doing some research on this topic, it looks as if ASP.Net evaluates the browser to determine whether or not it is AJAX capable. Whatever is being sent by WAPT is not being deemed AJAX capable. I have tried several settings in the WAPT User Agent settings: Mozilla/5.0 (compatible; WAPT; Windows) Mozilla/4.0 (compatible; MSIE 6.*) * IE 6.0 * The IE selections above should definitely be AJAX compatible, but no go.....still get the error. Any ideas would be appreciated. Thanks, Quote Share this post Link to post Share on other sites
