Performances are everything!
So every decent web developer probably know Yahoo YSlow and his ranking system.
One of this rule has been particularly a mystery in the last few months… ETag
If a site has multiple servers that serve files (i.e. load balancing), a user may request for the same file and get a response from different machines. If the inode is used to generate the ETag, it will be different causing the file to be re-downloaded.”
So how to disable ETags on IIS6? I’ve seen a lot of workaround, ISAPI filters, strange system configurations… until.. I’ve seen the light…

Hi Guys even no need to implement module to remove Etag just go to Inetmgr and add header in your web site Key = “Etag” Value = “” it will remove Etag from your .js,.Css and .image file.
Simply working and cleaver!
