How do I stop Opera from caching a page?

Question

I am trying to get Opera to re-request a page every time instead of just serving it from the cache. I\'m sending the \'Cache-control: no-cache\' and \'Pragma: no-cache\' res

Found this whilst searching for solution. No joy, so wrote some javascript to solve the problem which may be of use to others.

In above any other javascript:

Now change window name so Opera detects it on subsequent load from cache:

window.name = 'previously_loaded';

Insert this line in one of your js blocks that wont be executed during “window load” causing infinite reload. For me there was no need to refresh the page unless someone has exited by a link, so I just added it to my onclick/onunload function.

Before and after demos here with a few more notes. I intend to add it to my blog. I've only a few late versions of Opera, so I would appreciate some tries of the demo before I get egg on my face.

Edit: Just realised that if a later visited site changes window name (its persistent) then back-tab reload wont happen. Just alter above if statement to:

 if (window.name != "") {

Demo worked fine when open in multiple tabs; but I vaguely recollect that window names should be unique; so I've altered the demo to generate a unique name.

window.name = new Date().getTime();
