--------------------------+-----------------------------
 == Environement ==
 Windows Server 2008 (version 6, build 6002: SP2)
 IIS Version 7.0.6000.16386
 PHP Version 5.4.26
 FastCGI

 == Problem ==
 When uploading a media file to Wordpress the upload only runs for the
 max_execution_time set in php.ini. When that time has elapsed (for slow
 connections or a large file) the multi-file uploader displays the generic
 error "HTTP error." The browser uploader stops with the PHP error "max
 execution time reached"
 Is this behavior by design?

 == Proposed solutions ==
 1. '''set `set_time_limit(0)` in media-new.php, so a upload can take as
 long as it needs''' [[br]] For IIS this solution is preferred, because
 FastCGI automatically stops script execution when a connection is lost.
 For Apache the additional code `ignore_user_abort(false);` might be needed
 to prevent the script from executing after the client has aborted,
 although that also is the standard behavior for Apache I think.
 2. '''Display a more helpful error''' [[br]] "HTTP error." could
 practially mean everything. It took me at least 2 hours to find out what
 was causing the error. Displaying "Your upload exceeded the
 max_execution_time set in PHP" makes things already a lot more
 understandable.

 == Thoughts about limits ==
 File uploads are already limited by max_upload_size and max_post_size, so
 it should make sense to not also limit them on how long they can take.
 Some users simply don't have a fast enough connection to complete the file
 upload in the max_execution_time specified by php.ini
