Hi Mime type setting help needed!

Hi : I got an intranet application, My application is running on Apache7.2/php4/mysql through my application users can upload files in .wpd (word perfect 9) almost all the files are in wpd format. One of the other requirement is clients are all using netscape 4.7 When they try to view/open the uploaded file through browser it generate some garbage characters. Can anyone will be able to suggest a way out from this issue. They won't upgrade the browser i tried to change the mime type on our test machine (windows/apache/mysql) it works fine butwhen i tried the same thing over linux machine it didn't work out well. If any one can please help Thanks Prad __________________________________________________ Do you Yahoo!? Yahoo! Tax Center - File online, calculators, forms, and more http://tax.yahoo.com
