Prevent XML files from being cached by browser

[guvenck]

Hi,

I realized that my browser caches the xml files I am using in my project and loads them from cache. That is not good for me, especially when I experiment locally and need to edit XML file every minute :)

So, it should be possible to make the browser load the file itself each time the XML file is requested. How can I do this?

I found the cure:

The solution is to add a unique identifier while calling the file, at the end of the xml file.

In my case, the code is:


xmlDoc.load('../xmlfiles/'+xmlFile+'?uid='+new Date().getTime());


Hope it might help someone.

There's probably a better solution through HTTP headers (pragma: no-cache?).

I read somewhere that Firefox still shows the older XML file, when a header cache solution like yours is used.
