Can you check with a phpinfo()-page that zlib.output_compression really is set to "off" (otherwise try setting it to "0")? I can't reproduce the binary display with your example URL, it works with Mozilla 1.0 and lynx, if I make the HTTP by hand, it displays the correct headers. ------------------------------------------------------------------------ [2002-07-01 15:20:23] bugzilla@cm51-210.liwest.at i think the compressed data is the gzlib "dont compress, store only" header. browser is mozilla 1.1 cvs doesnt work with ie 6.0 either ------------------------------------------------------------------------ [2002-07-01 15:16:28] bugzilla@cm51-210.liwest.at if i compile with --with-zlib, output is zlib compressed (can check if i download page and gunzip) but browser displays binary output. (maybe content-type is wrong ?) zlib.output_compression is set to OFF (doesnt help) if i set zlib.output_compression_level = 0 output is readable, but prefixed with binary data ‹4(Ë×<?xml version="1.0" encoding="iso-8859-1"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> you can check by yourself: http://cm51-210.liwest.at/wiki/index.php?pagename=LinzCam ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=18095&edit=1
