AJAX: changing GET into POST result into page not found error

Copy linkTweet thisAlerts:

Hi All

I noticed that my ajax calls were cached by the browser. However I want to do an ajax call over and over again, retrieving the data from the server, not from the browser’s cache

I red somewhere that you can change ‘GET’ into ‘POST’, because the browser doesn’t cache POST-requests.

Here is my code (snippet):

[code]
xmlDoc = new window.XMLHttpRequest();
xmlDoc.open(“GET”, “config.xml”, false);
xmlDoc.send(null);
[/code]

changing ‘GET’ to ‘POST’ results in a page not found (404) error. Any suggestions?

Thnx a lot
LuCa

@aj_nscDec 06.2008 — I ran into this trouble before too, I make the same ajax call over and over again, however, I don't want it cached. There are object parameters you can set, but the way I do it is to append the "url" variable you are sending with the current unix time every time a request is sent, this tricks the browser into thinking that this ajax call wasn't made before and therefore, the response wouldn't be cached.

Like this:
<i>
</i> now = new Date();
url = "yoururl.php?plus=your&amp;parameters=here";
url = url+now.getTime();

//send your request here
