How to enable Gzip in IIS

Enabling gzip balances the server bandwidth and performance. gzip compresses the file to save a lot of bandwidth, but it also increases the server processing load, this can be balanced by yourself.

 

First, describe the server environment: Windows2003 + IIS + PHP + ISAPI Rewrite. Check that the iis configuration content is correct, but the Gzip status is not enabled when querying the HTTP status, today, when I access a Discuz forum On the server, the bottom line is Gzip On. Is Gzip in PHP conflict with IIS? Run the test, open the PHP configuration file, disable the extension of php_zip.dll, and restart IIS.

After the preceding operations are completed, the Gzip status is enabled. There was no problem with the batch file opened by Gzip. The problem was that Gzip was also enabled in PHP, And the IIS was in conflict.
