Hi,
it is not possible to force a target frame
via the header(location 🙂 funktion..
because displaying frames is a browserside job ...
Some versions of Netscape are accepting the
"window" parameter withhin header(location : ) as frame target ..
AFAIK : the only way to realize what you want is to use javascript ...(yes, i don't like it too)
If there is anyone outside how knows a better way -> please keep me informed !
bye,
Nikolas
