Turn off caching for Firefox

I have a need to turn off the caching for a particular page. I suppose the correct way is to set the cache directive in my Http request:

Cache-Control: no-cache

The server correctly returns the new version. The Firefox, however, insists to return me the cached old version.
So I have to turn the entire Firefox caching capability off through its about:config page
network.http.use-cache = false.

Too bad.

My first grease monkey script

I wrote my first grease monkey script today. It is to apply a XSLT style sheet on certain types of XML files. This is because usually the xml contains too much information and I just want ot view certain part of it and in more clean format such as a table. Here is the code:

xml transformer

This is a Greasemonkey user script for Firefox.

This script applies XSLT on plain XML files

// ==UserScript==
// @name xml transformer
// @namespace http://sample.com
// @description apply XSLT on plain XML
// @include http://localhost/*.xml
// ==/UserScript==

var contentType = 'text/html';

function detectFormats() {
// define classNames and URLs of corresponding XSLT files - edit this to add new formats
var b = new Array();
b[0] = new Array('Root1', 'http://localhost/gmonkey/xslt/root1.xslt', 'text/html');
b[1] = new Array('Root2', 'http://localhost/gmonkey/xslt/root2.xslt', 'text/html');

// look for certain signature in document
for (i=0; i<b.len; i++) {
var schemaType = b[i][0];
if (document.getElementsByTagName(schemaType).length > 0){
xsltURL = b[i][1];
contentType = b[i][2];

function fetchXSLT(url){
method: "GET",
url: url,
headers: {
'User-agent': 'Mozilla/4.0 (compatible) Greasemonkey',
'Accept': 'application/atom+xml,application/xml,text/xml',
'Cache-Control': 'no-cache',
onload: function(response) {
var xslt = new DOMParser().parseFromString(response.responseText, "text/xml");

// transform the document to RDF using the XSLT file
function transformXML(xslt){
var processor = new XSLTProcessor();
var dataXML = document;
var processed = processor.transformToDocument(dataXML);
var dataString = (new XMLSerializer()).serializeToString(processed);
location.href = 'data:' + contentType + ',' + dataString;
