Upon re-reading my posting (naturally AFTER I'd hit submit), I noted the think-o. My apologies. =Apollyon= ------------------------------------------------------------------------ [2003-08-21 04:31:10] phpbug at paypc dot com OK, let me put forth some declarations so we're talking apples and apples. My test method: echo -e "GET /legal/tester.php HTTP/1.1\r\nHost: 127.0.0.1\r\n" | nc 127.0.0.1 80 > dump I wish to eliminate any possible "post-processing" or browser-variations. IE: "nc" is netcat, a commonly available network tool. OK, onto the results of my tests. I copied and pasted sniper's code *EXACTLY* as presented, with whitespaces and line spacing as entered. I obtained identical results with both lynx and my netcat method, though lynx probably doesn't support HTTP/1.1 because there was an additional header. With Lynx Version 2.8.3rel.1: HTTP/1.1 200 OK Date: Thu, 21 Aug 2003 09:10:16 GMT Server: Apache/1.3.27 Ben-SSL/1.48 Connection-Type: Keep-Alive Content-Length: 4 Connection: close <<<<<<<<<<<<< Additional header Content-Type: text/html With netcat: HTTP/1.1 200 OK Date: Thu, 21 Aug 2003 09:10:55 GMT Server: Apache/1.3.27 Ben-SSL/1.48 Connection-Type: Keep-Alive Content-Length: 4 Content-Type: text/html In comparing the actual bytes sent over the wire against the advertised content-length, the Content-Length header is correct. If you wish to inspect my PHP build and setup configuration, you may do so at: <http://hollywood.paypc.com/config4phpbugmasters> (I will be removing this after 24 hours.) And yes, it's pretty loaded. And yes, trans_sid is enabled, but in all of my test harnesses which employ sessions, I've enabled cookies - and they are created/used by the browsers involved. ******* AHHHHHHAAAA ******* Arigatoo gozaimashita to Moriyoshi-san for cautioning me to turn on trans_sid, because when I disable it in my global php.ini, the discrepancy disappears! For my "complex" web-application which formerly reported bad sizing, I received the following header (after turning off trans_sid): ---------------------------- HTTP/1.1 200 OK Date: Thu, 21 Aug 2003 09:20:47 GMT Server: Apache/1.3.27 Ben-SSL/1.48 Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Set-Cookie: PHPSESSID=a1c8bfb3f409580e57206d7c19eac473; path=/ Expires: Thu, 19 Nov 1981 08:52:00 GMT Content-Length: 2825 Content-Type: text/html -------------------------------- And doing a wc -c on the content-portion matches this size exactly (with my netcat test). Third-party validation via usage of <http://www.ircache.net/cgi-bin/cacheability.py> confirms an exact match of advertised Content-Length and what's actually received. And lastly, and most importantly, the IE "hang" bug while accessing this web application via an intranet is gone. OK, fine, trans_sid broke it. Why? And should it have? I'm suspicious that the Esteemed Moriyoshi-san nailed this specific setting in advance, as if to suspect it being a potential cause for buggage. Inquiring minds want to know - if it's by design, please add it to the documentation and FAQ. I know alot of things about the ob_ functions are unusual and cause some people hardship (of their own making). This one came out of left field. =Apollyon= ------------------------------------------------------------------------ [2003-08-21 00:10:00] [EMAIL PROTECTED] > Set-Cookie: PHPSESSID=2989258979bd07405999448563ef4bfc; path=/ Perhaps you seem to have enabled session.use_trans_sid. If so, first turn it off before trying the above script provided by sniper. ------------------------------------------------------------------------ [2003-08-20 22:54:00] [EMAIL PROTECTED] try this script: <?php ob_start(); ?> foo <?php header("Connection-Type: Keep-Alive"); header('Content-Length: ' . ob_get_length()); ob_end_flush(); echo ob_get_length(); ?> And access it with this command: # lynx -head lynx -dump -head http://localhost/test.php I get this (correct) output: HTTP/1.1 200 OK Date: Thu, 21 Aug 2003 03:52:44 GMT Server: Apache/1.3.27 (Unix) PHP/4.3.3RC5-dev X-Powered-By: PHP/4.3.3RC5-dev Connection-Type: Keep-Alive Content-Length: 4 Connection: close Content-Type: text/html ------------------------------------------------------------------------ [2003-08-20 07:05:31] phpbug at paypc dot com Description: ------------ Very straightforward. I have a preamble and postamble include on ALL of my main .php pages... which use ADODB session management, some PEAR, and other typical dynaweb goodies. The Content-Length header is *ALWAYS* off by about 81 bytes, as in, the ob_get_length() is always smaller than the actual size of the content sent... I've verified this with "netcat" - after trimming the headers from the reply, the content is 81 bytes larger than advertised in the Content-Length header. I observed no change in behaviour after adding the ob_clean() call into my header file. OTHERWISE, things work fine. What's the deal? Is Apache silently adding CRLF's? I am NOT using the gzhandler or transparent compression here. This is just straightforward output. =Lord Apollyon= Reproduce code: --------------- The code for all of my index.php's consist of the following: <?PHP include_once 'db_header.inc'; ................ include_once 'db_footer.inc'; ?> db_header.inc: <?php $start_time=gettimeofday(); ob_clean(); // paranoid and desperate ob_start(); header("Connection-Type: Keep-Alive"); ?> db_footer.inc contains: <?PHP if ($LOGGING) { $LOG->close(); $LOGGING=FALSE; } header('Content-Length: ' . ob_get_length()); ob_end_flush(); ?> Note: there are no blank lines at the beginning of my *.inc or *.php files. Expected result: ---------------- I would expect Content-Length to reflect the actual output size. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25175&edit=1
