note 46068 rejected from ref.zlib by betz

Note Submitter: sit1way at hotmail dot com ---- Hey all. I've run into a problem using zlib compression & Apache's ForceType directive. The problem: Internet Explorer 6.0+ users are getting a download prompt, the d-loaded file contents being 5k of compressed data which IE , for some reason, isn't able to interpret/decompress. I'm running RedHat9 with PHP 4.3.8, Apache 2.0.51, MySql 4.0, & Zlib 1.1.4. My httpd.conf has Forcetype directive set as follows: <FilesMatch ^(view)> ForceType application/x-httpd-php </FilesMatch This allows for urls in the format of domain.com/view/var1/var2/ to be evaluated as view.php, & the vars accessed via script path_info. My php.ini file has the following zlib settings: zlib.output_compression = On zlib.output_compression_level = 6 and my view controller script has the following to send gzip compressed content: ************************************************* <? session_start(); /* Start output buffering */ ob_start(); ob_implicit_flush(0); /* get some content */ php code to get content here /* Get buffered content */ $contents = ob_get_contents(); ob_end_clean(); /* If browser accepts compression, compress it */ if(ereg("gzip, deflate",$_SERVER['HTTP_ACCEPT_ENCODING'])) { header("Content-Encoding: gzip"); echo "\x1f\x8b\x08\x00\x00\x00\x00\x00"; /* Figure out the size and CRC of the original for later */ $Size = strlen($contents); $Crc = crc32($contents); /* Compress the data */ $contents = gzcompress($contents, 9); $contents = substr($contents, 0, strlen($contents) - 4); echo $contents; function gzip_PrintFourChars($Val) { for ($i = 0; $i < 4; $i ++) { echo chr($Val % 256); $Val = floor($Val / 256); } } /* Output the CRC, then the size of the original */ gzip_PrintFourChars($Crc); gzip_PrintFourChars($Size); } else { echo $contents; } ************************************************* In other browsers (e.g. Mozilla, Opera, etc.), the forcetype/zlib combo works flawlessly; however, IE, still unfortunately the major player in browser market, is screwing up something, or I'm doing something wrong on my end -- I just don't know what that might be! If anyone has encountered this issue, please, please let me know. I don't want to drop zlib, it's way to useful an extension to drop.... TIA, --Noah
