-      <p>Some popular browsers cannot handle compression of all content

-      <p>For browsers that have problems even with compression of all file

-      note for that particular browser so that no compression will be
-      performed. You may combine <code>no-gzip</code> with <code

-      <p>At first we probe for a <code>User-Agent</code> string that
-      indicates a Netscape Navigator version of 4.x. These versions
-      cannot handle compression of types other than
-      <code>text/html</code>. The versions 4.06, 4.07 and 4.08 also
-      have problems with decompressing html files. Thus, we completely
-      turn off the deflate filter for them.</p>
-
-      <p>The third <directive module="mod_setenvif">BrowserMatch</directive>
-      directive fixes the guessed identity of the user agent, because
-      the Microsoft Internet Explorer identifies itself also as "Mozilla/4"
-      but is actually able to handle requested compression. Therefore we
-      match against the additional string "MSIE" (<code>\b</code> means
-      "word boundary") in the <code>User-Agent</code> Header and turn off
-      the restrictions defined before.</p>

       <note><title>Note</title>
         The <code>DEFLATE</code> filter is always inserted after RESOURCE
         filters like PHP or SSI. It never touches internal subrequests.
