Issues with redirect

[am1971]

Hi

 

Once a customer logs in, they are redirected to the main page ....index.html, how to I redirect a customer directly to their account ...account.php.

 

 

The same question goes for affiliates, after signing up or signing in they are redirected to the main page how to change it to the affiliate account.

 

So basically my question is where will I find the involved files with redirects.

 

And how do I change them.

 

Thanks
