ASP.NET MVC Upload file time out

Question

I currently have an ASP.NET MVC project that has file uploading and it works great if the user has a good enough connection and their file is of a reasonable size.

The problem I'm running into is that sometimes a user might have a 56k connection (how they can live with it in this day and age, I don't know) or are uploading a larger file or some combination of the two.

I'd like to keep a small timeout for normal pages (90 seconds or so), but allow for a larger timeout for actions where a user is uploading. This is just one action, so I don't mind putting code inside just that singular action rather than a generic solution.

Ultimately, a solution that would automatically increase the timeout if Request.Files.Count > 0 would be the best.

What is timing out? If you're not getting anything from the client after 90 seconds or so, you're probably not going to successfully upload anything. — chris

I am continuously receiving data, chris, but sending even 10 megs over 56k will take over 90 seconds. — ckknight

I'm not sure if this would work in an MVC project, but you could try creating a location in your web.config and set the execution timeout for just your upload URL. For example:

<location path="YourUrl">
  <system.web>
    <httpRuntime executionTimeout="9001"/>
  </system.web>
</location>

This works. You can also add maxRequestLength here (on the httpRuntime tag) if you want to allow larger requests to the upload handler only.

his execution timeout is over 9000!

9000 seconds is 2 ½ hours! What a timeout.

You might need to increase the timeout in web.config:

<httpRuntime executionTimeout="01:00:00" />

Now this is overridable in sub web.config files meaning that if you want to increase the timeout only for the uploading script you could write a generic HTTP handler that will handle the uploads and put it in its own subfolder with its own web.config.

Possible issue: If its not a timeout because of the zero activity, maybe its something to do with the built in size restriction, in the web.config httpRuntime section you could add/increase maxRequestLength="" to your size limit
