What is the cause of a timeout error using input type="file" in classic asp site?
We have recently started experiencing timeout errors on an old (very old - 11 years!) portion of our website that we use internally, to maintain some content on another part of our site.
Basically the page involves browsing for a file and uploading it, with a link for users to view that file.
Whenever the file we select (using the input field) is large (say 10mg) and we submit the form, IE (or Chrome) times out. If we choose a small file (a few 100 kb) it works correctly.
I have narrowed the issue down to the use of the input type="file" element in this classic asp page.
I can reproduce the scenario with the most basic of HTML as follows;
<html>
<body>
<form id="myForm" name="myForm" method="post" enctype="multipart/form-data">
<input type="file" size="50" id="Test" name="Test" value="Test">
<input type="submit" value="Test">
</form>
</body>
</html>
Selecting a small file here simply posts back and clears the form, while a large file appears to hang before reporting a timeout error.
I've tested this on IE9 and Chrome.
We have only just started experiencing this error - we don't even use the feature all that much but I would hazard a guess and say the last time anyone used it correctly was probably using IE8.
I am now going to attempt to test using older browsers.
Does anyone know what could be causing this behaviour?
So far I've searched IE 9 options for settings that may be affecting the timeout but none have jumped out at me. I've looked quickly at IIS settings too but nothing seemed obvious however I am far from an expert in this area (the server runs IIS 6 but we've reproduced this in a test environment running IIS 7 as well).
[Update]
Thanks to the suggestions so far, I have now tried;
- Resetting the file upload limit in the ASP config settings on IIS
- Adjusting the ASP timeout value on IIS Temporarily disabling
- Anti-Virus on the server and client.
(None of these have resolved the pro开发者_如何学Goblem.)
Try adjusting the ASP time-out...

I've had similar issues with large files in the past, many years ago with classic ASP, I've also seen this issue when a file is larger than the IIS upload file size. Hopefully, one of these two settings should let it work for you...
