If you wish you could use lesser bandwidth while downloading web pages and improve the download speed, get the ETagFix.
This is an ISAPI plugin which integrates with IIS and other web servers so that the etag is altered. This utility can be used as an add-on for Microsoft IIS or any other web servers. As etags for the web pages downloaded change often, these pages are downloaded again. This utility can fix the problem with etags thereby avoiding web crawlers from consuming your bandwidth even if the web pages have not changed at all. This tool has a GUI configuration tool which allows you to configure the application’s many features. The program is easy to install and the un-installation removes all traces of the program.
ETagFix is compatible with almost all browsers. It saves your bandwidth, system time and money by fixing the etag program.
