88	Accept-Encoding: gzip;q=0, deflate	dartar	DotMG	"(reported by DotMG)

''Not really  bug, but should be corrected for respect & compliance to RFC2616''

If a browser sends the header 
{{{
Accept-Encoding: gzip;q=0, deflate
}}}
Which should be interpreted as : ""I don't support gzip encoding, but I prefer deflate"", Wikka will understand ""The browser supports gzip-encoding"", as it just searches for the text gzip in $_SERVER['HTTP_ACCEPT_ENCODING']. An example I use to treat it correctly is :
{{{
function ParseHeaderLine($hl, $token=null)
 {
  $ar_hl = explode(',', $hl);
  foreach ($ar_hl as $dotmg_idx => $val)
  {
   if (preg_match('/^\s*(.*?);\s*q\s*=\s*([0-9\.]*)/i', $val, $match))
   {
	$res[strtolower($match[1])] = doubleval($match[2]);
   }
   else
   {
	$res[strtolower($val)] = 1;
   }
  }
  if ($token) return(isset($res[$token]) && ($res[$token] > 0)); #if $token is set, we return true or false
  return ($res); # else we return the header parsed.
 }
}}}
and
{{{
if ($this->ParseHeaderLine($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip')) ...
}}}

'''Note''' : This function might be useful to deal also with Accept-Language, when Wikka will be made effectively multilingual.
