OOCalc Mime Type

[FYZ]

Need help, I want to open HTML table with OOCalc from Firefox and I used

header("Content-Type: application/vnd.sun.xml.calc")

I think its a correct mime type for OOCalc, but why Firefox does not recognized it and always triggering OOWriter to run. I tried mozilla with the same result as Firefox.
Is there any other mime type for OOCalc ? are there any way to force firefox/mozilla to open openofice document in their (OO) original windows not in firefox/mozilla windows ?

for your information I am using suse9.3 and firefox 1.0.6

Thanks

My PHP Program is look like this one, the problem is spesified MIME type cannot open OOCalc directly, but always triggering OOWriter to run. In MS Windows environment I can opening MS Excel directly with the excel mime type.

<?php
header("Pragma: public");

    header("Cache-control: private");

    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');

    header("Expires: Tue, 1 Jan 1980 12:00:00 GMT");

    header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");

    header('Connection: close');

    header("Pragma: no-cache");

    header("Expires: 0");

// header("Content-Type: application/vnd.ms-excel");

// header("Content-Type: application/vnd.oasis.opendocument.spreadsheet");

    header("Content-Type: application/vnd.sun.xml.calc");
