.NET Forum / ASP.NET / Caching / November 2004Caching .xml and .xsl files
Hi We use few .xml and .xsl files in our web application and we found that these files even though fairly static gets downloaded to the client's machine everytime the page is refreshed. Is there a way we can instruct so that these files only gets downloaded to the client's machine if there is an update to these files. Please help Rahul Yes, you can set the page expiration settings in IIS to the default values, or tell the browser to cache them for 4 hours, 1 day, etc. Note that if a user refreshes a page their browser may download those files anyway.

It's possible that this section is set to "Expire Immediately" which will cause users to download the pages every time. You can uncheck "Enable Content Expiration" so that browsers will only download the files if they change, or check "Enable Content Expiration" & set a specific expiration value.
