Question

I am using the ASP.NET GeneratedImage control (http://weblogs.asp.net/craigshoemaker/archive/2008/08/19/new-asp-net-generated-image-control.aspx)

The image handler seems to receive multiple requests at once from the same client and then the application_error is called multiple times at once (because there are multiple images on the page). Is this correct? For example, if a web page contains three images, then the Image Handler is called three times almost all at once (after the page is loaded). This is happening when I step through the code.

My question isn’t about why I am receiving the error, but why the image handler seems to receive multiple requests for images at once.

Answer 1

Any ASP.NET handler may be called on multiple threads, so yes, it may be called multiple times “at the same time”.
