I'm looking into adding RSS feeds to my site's (investment site) daily top 10 list. Does the XML page with the feed data need to have the .xml file extension in order to be utilized by search engines and/or individual users? I'm wanting to write a quick .NET page that'll poll my database for the data, and build the XML dynamically. The file extension will be .aspx. Thanks in advance
there will be no problem if it is with .aspx extension. go ahead with it. only, remember to check your feed with feed validator http://feedvalidator.org/
