Thanks.  I have read it. Very good.

Here is the result status by method 1;

A) GET /liwen/index.htm HTTP/1.1" 200 808 mod_gzip: OK In:572 -< Out:380 =
34 pct.

B) GET /index.php?file=company/contact.html HTTP/1.1" 200 17993 mod_gzip:
     SEND_AS_IS:HAS_CE In:0 -< Out:0 = 0 pct.

C) GET /liwen/php/mail.php HTTP/1.1" 200 818 mod_gzip: SEND_AS_IS:HAS_CE
In:0 -< Out:0 = 0 pct.

Here is the result staus by method 2;

      In:0 -< Out:0 = 0 pct.

 B) GET /index.php?file=company/contact.html HTTP/1.1" 200 18263 mod_gzip:
      SEND_AS_IS:HAS_CE In:0 -< Out:0 = 0 pct.

HTTP/1.1"
      200 4079 mod_gzip: SEND_AS_IS:HAS_CE In:0 -< Out:0 = 0 pct.

Transparently, Gzip didn't compress PHP code by Method 1 and 2.  BTW, Gzip
didn't compress HTM by Method 2 (Method 2A).

Here is my part of mod_gzip.conf.

mod_gzip_item_include         file       \.html$
mod_gzip_item_include         file       \.htm$
mod_gzip_item_include         file       \.php$

mod_gzip_item_include         file       [^.]*$
mod_gzip_item_include         file       \.js$

mod_gzip_item_exclude        mime       ^image/.*$
mod_gzip_dechunk              Yes


Might my configuration be wrong ?! Any comment ? Thanks in advance.
