closing httpd connection, before end of script

[BlakMonk]

Hi,

Is it possible to close the httpd connection and carry on with the rest of the scipt ? I'm currently trying to do it in PHP.

In more details, I want to :

- treat the received parameters
- display stuf
- Close httpd connection so web client can continue
- in the back ground do stuff on the scirpt

Can it be done ?

What scripting language are we talking about here? Or are we just talking in general?

Edit: I see in the original post it says "PHP". I didn't see that before.

Well,

This perticular case, in PHP. I have a way to do it in mod_perl, but the current script I'm working on is in php.


Any ideas ?

Yes, actually. I have been reviewing the php manual and looked at all sorts of output functions and ways of controlling the socket connection. Unfortunatly, I need to experiment with it in order to understand exactly how it works.

There is one solution that's pretty simple - use output buffering to send your output to the browser and close the connection:

<?php
header("Connection: close");
ob_start();

echo "This is output to browser";

$size=ob_get_length(); 
header("Content-Length: $size");
ob_end_flush();
flush();

// Anything done here is done after output is sent to browser.

?>

Does this make sense? I could be off track here. I still am wondering if the connection to the client is indeed closed with this script.

Hi,

I must admit, that is quite a clever way to do it. But I already use the ob_* functions to trap errors that would happend with "eval"...

Come to think of it... Yes it could work, I'll regroup all my displaying.. and see where it leads...

I'll keep you posted.

hi,


I tried it, I had to do some MAJOR modifications on my logic, but it works!

Thank you very very much for your help!
