Betreff:    [TYPO3-english] Problem with alt_mod_frameset.php
> Hello,
> I'd like to use the class-file /typo3/alt_mod_frameset.php for an own 
> class in an own main-modul.
> Until now I have some problems with that because of different reasons:
> 1) The class-file alt_mod_frameset.php (and a lot of other files in 
> /typo3/) has inclusions of files by "require ()"
>     Including the file in another class throws an error about 
> double-loaded functions. Under this circumstance the class should 
> include files by "require_once()"
> 2) The class serves as source of several mods, but is there referenced only.
>     Intantiation is done in the class-file itselfe. This makes it hard 
> to change some parameters but see next point ....
> 3) Parameters are taken from GPvar, so it's not possible to instantiate

> 4) I know classes should be called with mod.php but I don't know how

> 5) I can't and dont't want to configure it as frameset for the whole 
> mainmodule in ext_localconf.php so I have to call it in another way.
> I've build a working frameset by copying the file in my own extension

solution for my question is to set a new header in the calling file / class.
To avoid getting two headers while the first one produces a 404 Error 
for the calling class I set also a 302 Header (Redirect), so only one 
file for the frameset is submitted to the browser:

// setting parameters and build URL
$script = 
$nav = 

$URL_nav = 

// setting Headers
header("HTTP/1.0 302 Redirect");
header('Location: '.$BACK_PATH.'alt_mod_frameset.php?'.$URL_nav);

This Method you can use from any class and doesn't need further 
configuration of any variables.

If you get any 404-Errors:
- check the path-values for your files (pathes for your own files have 
to be noted relative to /typo3/- directory)
- check the signs '?' and '&' in your URL (often between the URL and the 
parameters a "&" may be noted instead of "?")
