Bizarre IE behavior

[CoderMan]

I have a web site with download links. Downloads are segregated according to different file types. Files of a file type are grouped together and are displayed in a drop down list box. User selects the file required and then hits go and the file downloads.

For ex. The first drop down contains all gif’s, the next drop down all jpges….

One such drop down contains IGES(Initial Graphics Exchange Specification) files with extension .igs

When users try to download these .IGS files and they do not have a MIME type associated with this file, they should be prompted to download the file. Instead however the text version of the file is displayed. This happens only for users using IE (either 5.5 or 6.0, no information about other IE versions). It does not happen when users using NN. The other funny thing is it happens only when the files in question are on a NAS device. If I move the files over to some regular server using Win2k, it works just fine.

All other file extensions work just fine. Right clicking and choosing ‘Save As’ is not an option as this doesn’t work because of the javascript associated with clicking the ‘go’ button.

Does any one have any idea? Any help would be appreciated. Thanks in advance.

I made a mistake in my previous analysis. It's not NAS that's causing the behaviour but anytime we access the file thorugh IIS.

If I access the IGES file as

http://www.abc.com/file/sample.igs

then I get the problem.

If I go to the server and then browse for the file as

C:\Inetpub\

http://wwwroot\files\sample.igs

then it prompts me for a download.

Hi CoderMan,

There is a quick fix to your problem. Try zipping (.ZIP) the files as they are generally in the default MIME list will eleminate the download issue.

Hope it helps!
