I am writing a mod_perl2 apache handler...
I was performing some form data parsing and feeding the data to mysql database.
I was also working on a progress indicator. This is where im having the problem.
I cant seem to figure out how to get apache to dynamically feed the status messages
directly to the browser / client. Ill try to elaborate on this.
I want the page that is generated to have status messages print, to correspond to the
give tasks that are being performed and their resulting success or failure. Of course
i can generate the output and print it to the client, but it ALL gets printed at once,
on task completion. Quite a bit of time passes by whenthe script is running and i would
like the messages to be printed progressivly as the script executes.
I have seen this feature used on other sites and i have analyzed the output given by
the servers. It seems as if the server prints the content length before each line.
Im not sure where my problem lies... STDOUT buffering ? or using the RequestIO modules
$r->puts() or $r->write() methods. Or perhaps setting the content length for each
line / message printed ?
I have googled for hours, experimented and have gotten nowhere.
Any ideas are appreciated.
