Have the size limitation about FileUpload

[ad]

Have there any limitation about the size of the file uploaded by FileUpload
control?

This is limited first by IIS and/or web.config (the default is 4 Mo). If I
remember it was improved in 2.0 but was limited in 1.1 by the available
memory (the whole file was loaded in memory whihc could be a problem for
huge files).

I would do the other way round. Do you have a specific problem ?

I have a text file of 18M, which is SQL script.
I upload it with UploadFile, then read it with a StreamReader.
I have test to files, one is 5M, it ok, but another one is 18M, it result in
an error page: page not found.

How can I do?

Ad,
There is a maxRequestLength setting in the HttpRuntime section of
machine.config that is set to 4MB. You can override this in the web.config.

Have you checked the IIS log to see the status ? If this is not the size
limit, it could be perhaps also the script timeout (so the request ends and
its is seen client side as a response that you can't get ?).
Do you have a firewall (we had once a firwall that blocked jpeg images
against the jpeg vulnerability).
