#39284 [NEW]: sessions start with javascript in header causes refresh to not work in IE 7

From: paul dot visco at roswellpark dot org Operating system: Windows Server 2003 PHP version: 5.1.6 PHP Bug Type: Session related Bug description: sessions start with javascript in header causes refresh to not work in IE 7 Description: ------------ Pages using PHP sessions and external javascript in the head portion of the html document and which served from IIS 6 to IE 7 are not refreshing properly (displays blank on refresh). I have a full description of it here including the minimal source to create the error. Description, source and work arounds that may shed light on the problem: http://durge.roswellpark.org/ie7Bugs/ I think it has to do with IIS not reporting Content-Length because if I buffer all output till the end, set Content-Length header and then echo buffer to client it works. e.g. work around http://durge.roswellpark.org/ie7Bugs/sourceWithOutputBuffering.php Reproduce code: --------------- Source with description: http://durge.roswellpark.org/ie7Bugs/ <?php session_start(); ?><html> <head> <script type="text/javascript" src="javascript.js"></script> <title>IE 7 false content-length - refresh bug demo</title> </head> <body> <h1>IE 7 Content-Length Bugs</h1> <p>This will not show up on refrrsh when served from IIS 6 with PHP 5.1.6 to IE 7.</p> </body> </html> Expected result: ---------------- The page should display the text on load and on refresh. Actual result: -------------- The page does not refresh properly when served from IIS 6 to IE 7. Look fine on first load, but appears intermittently blank on refresh. Works fine in firefox and IE 6. it only happens when there -- Edit bug report at http://bugs.php.net/?id=39284&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39284&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39284&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39284&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39284&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39284&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39284&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39284&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39284&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39284&r=support Expected behavior: http://bugs.php.net/fix.php?id=39284&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39284&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39284&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39284&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39284&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39284&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39284&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39284&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39284&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39284&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39284&r=mysqlcfg
