If I do not have access to the web server configuration files, how would I know what HTTP headers are being used to download files?
I am talking about files that are downloaded by the browser, not displayed in the browser view port.
I am aware that some tools, like Firebug (and other browser extensions), will show headers for files loaded into the browser view port (e.g. HTML pages and images) but they don't - as far as I can see - display this information for files that are downloaded.
3rd party tools would be useful, preferably free.
I know asking the web host is one answer but it's not the one I am looking for (unless it's the only one) :-)
