[TYPO3] adding to query string

[La Farge Douglas]

Hi All,

(sorry if this is a repeat - i can't help but wonder if the mail  
server problems kept this from being sent out)

I need to add parameters to the query string that is passed to each  
page within the site I'm am helping to develop.

As we all probably know the current query string takes the form:

index.php?id=<somenumber> (eg index.php?id=1).

I need the form:

index.php?id=<somenumber>&brand=<someword> (eg index.php?id=1&brand=foo)

I have an external redirect (http://) set up for the home page that  
writes the additional parameter to the query string (which I then test  
with a series of conditionals).  However, the links within the page  
that is rendered loses the additional parameters (makes sense). So,  
how does one tell T3 via TScript (?) to include additional query  
parameters?

Thanks,

~doug
