Well it seems it's only the Gziped buffer to be sent without the Content-Encoding header.
These are the kind of things happening when using ob_start

I suggest you check you includes/page_header.php and page_tail.php, around :

Code: Select all

if ( $board_config['gzip_compress'] )

for header and

Code: Select all

if ( $do_gzip_compress )

for tail, and check if you have the correct 2.0.21 code here.
But I am pretty sure the Gzip handling was modified by the able2know mod rewrite, so it's not necessarily going to be easy to fix that.

Anyway, with Gun-zip, it's only a matter of resources (will take more) vs bandwidth (will need less), meaning you can leav without.

Maybe the simplest method to fix this will be to migrate to one of the phpBB SEO mod rewrites

hımm

big thanks dcz.

I'm using phpBB 2.0.21 .

Code: Select all

if ( $do_gzip_compress )

already added. BUT mixed AND arduous

dcz please see my files check please
www.lavinya.net/2.zip (page_header and page_tail)

[lavinya]

sorry dcz. small english

using seslisozluk.com

So it seems Gun-zip never was available with the abl2know mod rewrite as it's code :

Code: Select all

if ( !$userdata['session_logged_in'] )
{
$contents = ob_get_contents();
ob_end_clean();
echo replace_for_mod_rewrite($contents);
global $dbg_starttime;
}

is destroying the buffer (ob_end_clean(); ) before it is eventually sent Gunzipped.

You can try :

Open :

Code: Select all

includes/page_tail.php

Find :

Code: Select all

if ( !$userdata['session_logged_in'] )
{
$contents = ob_get_contents();
ob_end_clean();
echo replace_for_mod_rewrite($contents);
global $dbg_starttime;
}

//
// Compress buffered output if required and send to browser
//
if ( $do_gzip_compress )
{
   //
   // Borrowed from php.net!
   //
   $gzip_contents = ob_get_contents();
   ob_end_clean();

   $gzip_size = strlen($gzip_contents);
   $gzip_crc = crc32($gzip_contents);

   $gzip_contents = gzcompress($gzip_contents, 9);
   $gzip_contents = substr($gzip_contents, 0, strlen($gzip_contents) - 4);

   echo "\x1f\x8b\x08\x00\x00\x00\x00\x00";
   echo $gzip_contents;
   echo pack('V', $gzip_crc);
   echo pack('V', $gzip_size);
}

Replace with :

Code: Select all

// www.phpBB-SEO.com SEO TOOLKIT BEGIN
if( function_exists(ob_gzhandler) && $board_config['gzip_compress'] == 1)
{
   if ( !$userdata['session_logged_in'] )
   {
      $gzip_contents = replace_for_mod_rewrite(ob_get_contents());
   }
   else
   {
      $gzip_contents = ob_get_contents();
   }
   ob_end_clean();
   ob_start('ob_gzhandler');
   echo $gzip_contents;
   ob_end_flush();
}
else
{
   $contents = ob_get_contents();
   ob_end_clean();
   echo $contents;
   global $dbg_starttime;
}
// www.phpBB-SEO.com SEO TOOLKIT END


I cannot test, as I do not run the able2know mod rewrite, but it should solve your issue

vavv

thanks dcz. you excellent.

now trying below code

[lavinya]

dcz error direct page (

click to www.lavinya.net/phpBB2/



now delete below code I back to old code

[dcz]

Sorry I forgot to mention you should as well delete this from page_header.php :

Code: Select all

//
// gzip_compression
//
$do_gzip_compress = FALSE;
if ( $board_config['gzip_compress'] )
{
   $phpver = phpversion();

   $useragent = (isset($HTTP_SERVER_VARS['HTTP_USER_AGENT'])) ? $HTTP_SERVER_VARS['HTTP_USER_AGENT'] : getenv('HTTP_USER_AGENT');

   if ( $phpver >= '4.0.4pl1' && ( strstr($useragent,'compatible') || strstr($useragent,'Gecko') ) )
   {
      if ( extension_loaded('zlib') )
      {
         ob_start('ob_gzhandler');
      }
   }
   else if ( $phpver > '4.0' )
   {
      if ( strstr($HTTP_SERVER_VARS['HTTP_ACCEPT_ENCODING'], 'gzip') )
      {
         if ( extension_loaded('zlib') )
         {
            $do_gzip_compress = TRUE;
            ob_start();
            ob_implicit_flush(0);

            header('Content-Encoding: gzip');
         }
      }
   }
}

And find :

Code: Select all

if ( !$userdata['session_logged_in'] )
{
ob_start();

and replace with :

Code: Select all

ob_start();
if ( !$userdata['session_logged_in'] )
{

as we are now handling Gun-zip through ob_gzhandler which does all the header sending and such.

thanks for reply

dcz I added below all code
forum is working.

but I surfing my forum
certain times topic or post click this error:

[dcz]

Must be your server having trouble with gun-zip and ob_start then. It's very common.

I think you have no choice but to turn it off and go back to original code then, or give a try to the phpBB SEO method, since you can migrate with no trouble if we setup the correct redirections.

[lavinya]

OK. thanks dcz for quickly your reply messages


can you look at this http://www.phpbb.com/phpBB/viewtopic.ph ... 466#257466

he solved that problem at this link.

[dcz]

That's the problem with ob_start(), if a mod adds other things in the buffer and such. With what I suggested there should not be any more issues, but who knows.

Anyway, the regular phpbb ob_implicit_flush was already taken out in the code changes I sent, so beside migrating ...
