graceful file upload limit error?

Is there anyway to gracefully catch a file upload limit error? When the
limit is exceeded, IE displays a generic "Cannot find server or DNS error"
message.

no. the only way a webserver can stop an upload is to close the tcp
connection, as the protocol is so simple. IE just shows a generic message,
other browsers may be more informative.

I have a series of .net file upload pages i've written that validate the
posted file size, before it is saved. Keep in mind that it is posted to
the server side and the server side is then validating the file
size...not the most efficient solution but it works. I can show you my
approach if that's specifically what you're looking for.

3rd party controls can do it (for a price).
Nothing built -in.

One trick is tell the user of the site that the limit is 6MB.
Then set your web.config file to 8MB.

Allow the file to be fully uploaded, then check its size and if it is
greater than 6MB send your friendly error message.
Obviously, you get the "standard" screen if the file is over 8MB.
But you get the idea.

Are you saying this will catch it before the maxRequestLengt h is reached?
So if the file is 10 MB and maxRequestLengt h is 5 MB, your code will display
an "error" message?

Sorry I misunderstood you. I have a similar design to what you have
right now. So I have the same issue that you have I would imagine.

Hello, I want to upload files via an HTML form and store them somewhere on my webspace. So far so good. I am just a bit concerned about security issues and traffic. My provider has set a file size limit of 20MB in php.ini. My questions are: 1) If some evil web terrorist tries to upload a file which is larger than the maximum allowed by the setting in php.ini - will the transfer be cancelled by the server when the limit is reached so...

Hi there, When adding a "File Field" HTML control to an aspx page to facilitate file uploading, the following occurs: 1. You select a file that is larger than the allowed size limit. 2. Once the user selected the too large file, the page is redirected to a "page not found" error page. 3. This is as per the docs, but my question is:

I want to throw an error immediately if user is trying to upload a file of size greater than the specified limit. We are checking content-Length for this. But, if Im not mistaken, for large files the issue is because of the behaviours of HTML and Java: Once the user hits on upload button, the file is included in the request body as the enctype is multipart/form-data. If the connection is slower the time taken for a file >10 MBs is...
