blank label in some computer (.NET C# 2.0)

[newdriger]

There is an issue in my .NET C# 2.0 web application. All page labels are not hard coded by HTML due to multi-language support. So, the labels are come from a function call "UInterface " which will retrieve contents from resource files in App_GlobalResou rces folder.

Most of my customers do not have problem. But recently, few customers can't get content but blank space. Can someone help me out?

Does it show that the server was able to decide on a valid language for the user?
I *think* when a client browser makes a request, it sends a header line saying like "I use english and can handle html/text/gif/jpg/etc".
If for whatever reason that line is not present, or the language they sent is not understood by the server, it might not know how to handle it and just return blank strings with no content?

Is there like a "default" language that it can fall back on if it can't find a language match?

I use English content to test. Just show blank. I just wonder if there is some firewall setting to block this .NET UInterface func. I don't know. But 99% customers no problem in vary browsers.

Thanks for your reply!

Well if I am right and it uses the header, it might not get sent with HTTP/1.0 requests (IE used to default to using 1.0 through proxy servers).
Can you find some kind of common trait that the people experiancing the problem have?
