Edit report at https://bugs.php.net/bug.php?id=68778&edit=1 ID: 68778 Updated by: cmb@php.net Reported by: ingo dot flaschberger at openresearch dot com Summary: zlib.output_compression does not parse Accept-Encoding correct -Status: Open +Status: Verified Type: Bug Package: Zlib related PHP Version: Irrelevant Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2015-01-09 14:07:55] ingo dot flaschberger at openresearch dot com Description: ------------ In ext/zlib/zlib.c:static PHP_FUNCTION(ob_gzhandler) the HTTP_ACCEPT_ENCODING is not parsed. PHP only checks, if the string "gzip" oder "deflate" is inside the header and enables outputcompression if set. RFC2616 allows for example that a probability (q) is set, which could be also 0 (disable compression) but PHP will enable it. For example: Accept-Encoding: gzip;q=0.0 actual result: compressed output expected result: uncompressed output Accept-Encoding: thisisnotavalidgzipacceptencoding actual result: compressed output expected result: uncompressed output Test script: --------------- <?php ini_set("zlib.output_compression", "1"); ob_start(); echo "foo"; ob_get_clean(); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=68778&edit=1
