How to make Internet Explorer 7 display file, not ask to download

[roar123]

Hey. I've created some work forms with Infopath 2007. Then I published them on sharepoint, and sent the links in emails.

When you click the email links (a link to an .xml file), Internet Explorer always asks to "Download" and "Open w/ Infopath".

How can I make it so Internet Explorer 7 automatically just displays the .xml file in the browser. This works on firefox but not IE for some reason.

Thanks.
