Hi,
I'm having a buffering problem with following combination:
-Webserver: Apache 1.3.23
-CGI: PHP 4.2.1
-Client: IE 6.026 (but fails using others as well)
Description:
I want the output buffer of php being flushed to the client in a
time-consuming loop, using the flush() and/or ob_flush() functions of
php. The client recieves no output till the script is totally
finished.
Possible causes:
-is the php buffer function working properly?
Yes it is. When i start buffering some text i check for the size of
the buffer to grow, and it does. Then i flush it and i can see the
buffer size is 0. So this means that php sends the buffer to the
backend right?
-is the browser buffering?
Yes it does, but sending 300 bytes prior to the 'real' data fixes
that problem, as i could see on another server using the same
client, but differing versions of php/apache. (php 4.0.2/
apache 1.3.14). On this particular server it worked like a charm.
-is apache using gzip?
Yes, gzip is enabled.It is known for buffering output till a script
finishes, but i disabled gzip in httpd.conf for this particular
file, as shown below:
<IfModule mod_gzip.c>
<Location /export/home/'hostname'/htdocs/debug.php>
mod_gzip_on no
</Location>
</IfModule>
I think that this should do the trick. If not, how could i verify
gzip being disabled?
Question:
Does this (newer) version of apache/php has some defaults that enable it
to buffer output? If so how can i disable them for one particular
file/directory?
Thnx in advance,
Wildcard
