Im not familiar with the code you are talking about, but i can tell you briefly when this errro occurs: an http response consists of two parts a header and the body. Attempts to write a http header when one has already been written and the body started will cause an error. A common cause of this (other than just plain writing a header in the wrong place) is that one of the libs in your package has stray whitespace in it, eg even a single space char after the closing ?> tag
Where to look in your case?
"I:\ms4w\apps\appweb\htdocs\common\session\session.php on line 509 is
trying to send a session control header."
Theres where the header is attempted.
"headers already sent (output started at
I:\ms4w\apps\appweb\htdocs\index_spatialphtml.phtml:6)"
Theres were the unexpected http body chars were found. Thats where id be looking.
If its not whitespace, then you need a programmer. Good luck.
