Enable IIS6 GZIP, improve website open speed

IIS6 does not enable GZIP function by default, we need to manually configure, but he did not provide graphical configuration function, so, technical personnel like me have not considered using him Yesterday I suddenly saw this thought, maybe it was useful to me, but looking for it from the Internet, it is a bunch of manual methods, very troublesome, but I have studied the configuration file of IIS before: C:\\WINDOWS\\system32\\inetsrv\\ MetaBase.xml, so, I know that as long as it is the function of IIS, you can modify this file to complete it. So, let's start with this file. Search for a circle on the Internet and find a place according to the modification provided online. Something like ClickOnce, huh, I am looking for this, all the operations are in place, as long as the implementation of a VBS or CMD is configured, huh, huh.

Using Gzip compression will increase the CPU usage of the server but can reduce the data sent by the server to the client through compression. If Gzip is used, IIS will automatically detect when sending data to the client, if the client browser Support IE6.0, firefox Gzip, then use Gzip compression to transfer data, if not supported, use the normal way to send.

So, sum up his advantages and disadvantages, excellent: compression transmission, the speed is generally increased by 2 times. Lack: CPU usage will improve, but through my analysis, GZIP will only compress when accessing a page. Next time, if the page does not change, it will not be compressed unless it is using compressed dynamic files. To decompress.

The above is the method, save as a batch The command file is fine. The format is: adsutil.vbs
