Reading files with ASPX extensions

Hello

I am new to this form and fairly new to Apple Mac.
I have been trying to read files with ASPX extension and can't find the appropriate application to read these files.
Have tried the browsers, have tried text reader and Open Office with no joy.
This Microsoft extensions seem very popular at the moment and I don't have any problems on a windows PC but the Mac seems not to like them?

Any help would be most welcome.

"http://www.gov.im/residents/roadnotifications/Notification.aspx?id=2768" this is a file I could not read?

Thanks

John

This is a Web Site, you don't read aspx's they hand out HTML for your browser.

That site loads fine in my Safari.

Thanks for the advice Kaveman, It didn't work on Firefox and I have now sorted that!

very grateful for the help.
