.NET Forum / ASP.NET / General / September 2007does ExecutionTimeout include file upload time?
Hi, I am trying to investigate a problem reported by one of my users who received a "System.Web.HttpException: Request timed out." error trying to upload a large file into my asp.net 2.0 application. I have seen several blog posts and other articles implying that the ExecutionTimeout property includes the time taken to upload the file, whereas I had been of the opinion that the execution timeout only started ticking once the entire request had been received by the server, and my recent experiments would seem to back this up. Can anyone throw any light on this? Andy ok I have done some more experiments and it seems that the execution timeout does indeed include the time to upload the file I would like to allow the user to upload large files if required, but I do not want to just set the global ExecutionTimeout to some massiv value because I think the default value is sensible for all other requests. Is there any way to set the execution timeout differently on different pages? or to override it programmatically for an individual HttpRequest object ? TIA Andy > Hi, > [quoted text clipped - 11 lines] > > Andy Try but AFAIK in classic ASP, the Server.ScriptTimeOut was initialized for each request with the IIS default value. Changes to this value were only valid for the duration of the current request. Just try to set the value in page A and display the value in page B to confirm (or not) that the behavior is the same in ASP.NET... --- Patrice > ok I have done some more experiments and it seems that the execution > timeout does indeed include the time to upload the file [quoted text clipped - 26 lines] >> >> Andy hmm, I just looked up the documentation http://msdn2.microsoft.com/en-us/library/system.web.httpserverutility.scripttime out.aspx It says that ScriptTimeout only works when you have <compilation debug="true"> in the web.config so it won't be an option for my production application Andy > Try but AFAIK in classic ASP, the Server.ScriptTimeOut was initialized for > each request with the IIS default value.

ScriptTimeout is ignored (or rather it's set to 30.000.000 seconds, around 350 days) when debug is set to true, so that you can set breakpoints and do debugging etc without having the page timeout.
