load on favicon request

Understood, just one more quick question though. If the 404 page is the one
causing the file to fire again, which would make sense because it is a php
page,
why wouldn't the $_SERVER['REQUEST_URI'] kick back the 404 page
'/error404.php/'
instead of '/favicon.ico/'?

A favicon request is a request like any other. If the favicon.ico file doesn't
exist the request will trigger a 404 and your 404 handler will be run. The same
will happen if your main request tries to load images/css/js that don't exist,
so
you either need to make sure your main requests never generate a 404 or you
need
to make your 404 handler/prepend script smarter. You can have it check the
requested URI and skip doing whatever it is you don't want it doing multiple
times per page load. This isn't something we can fix at the PHP level. PHP is
doing what you are asking it to do here.

I do have a 404 handler pointed at a .php script but I didn't even think of
that
because I didn't think it had anything to do with a favicon. As for how the
web
server is configure I'm not sure because I'm on a managed server so I don't
have
that access. I will test it with out the 404 redirect and get back to you.

Wouldn't this only happen if you have your web server configured to send
favicon.ico request through PHP? Or, perhaps if you have a 404 handler pointed
at
a PHP script? In a normally configured web server I don't see this happening.

I was able to confirm the issue occurs across all browsers including firefox

Description:
------------
Pages that are loaded with auto_prepend_file and auto_append_file load multiple
times per page request if there is no favicon.ico located in the root
directory.
I believe this only happens with chrome and IE, have not been able to replicate
the issue with firefox.
You will see using this configuration, if you load index.php your database will
get at least 2 entries, one for '/index.php', and one for and one for
'/favicon.ico/'
This might just be a matter of appending the documentation if this is deemed
"not
a bug" because according the php.net manual auto_prepend_file and
auto_append_file
should function exactly as the require() function. However if this code was
put
in index.php as "require('prepend.php')" instead of being autoloaded it would
always only load once.
Test script:
---------------
.htaccess:
php_value auto_prepend_file /path_to_file/prepend.php
prepend.php:
<?php
$mysqli = new mysqli('localhost', 'user', 'pass', 'database');
$mysqli->query("INSERT INTO uri_test (uri, time) VALUES
('$_SERVER[REQUEST_URI]',now())");
?>
Expected result:
----------------
expected result is that the prepend.php file only runs once per page load.
Actual result:
--------------
prepend.php loads when the browser is seemingly requesting the URI for the
favicon.ico
