Handling Errors in Large File Uploads

Using IIS 6.0 / ASP.NET 1.1

My problem has to do with not being able to have custom
error handlers when the file size exceeds what the IIS is
configured to handle.

I do understand that one can change the attributes:
maxRequestLength (along with the executionTimeout) of the
httpRuntime section in web.config or machine.config to
control how much and (how long) to open up the IIS gates.

However, for the cases when the size is larger than this
configuration, we want to be able to install custom error
handlers. Is it possible to do so (it seems that IIS is
returning a generic error when this happens).

In my opinion this is a bug. Is anything being done to
fix this? Does 6.0 or its patches have anything (we could
use beta versions as well).

Thanks in advance,
Rajeev

I am not 100% sure I understand what you're saying... but I think I have an
idea of what could help you...

The metabase determines the limit for file uploads through asp in the key
ASPMaxRequestEntityAllowed

Try setting this to a higher number such as 1073741824

As far as putting in custom error handling inbetween IIS Source and the
metabase... I doubt it - I think you'd be better off getting the size of
the file (if possible) before it's uploaded - Does this make much sense?

Thank you,
