What is the difference between Ajax POST and GET

Hi Everybody,

As all knows the difference between GET and POST is in the way how
the data is transfered,

But in case of ajax Though it may be a post Request we need to
format a querystring manually and send with the url,

My question is there any other way that without sending the query
string can we get the post values as in a normal form submit.

regards
Moses

I only see difference when you retrieve data in PHP/servers side.
i.e $_POST and $_GET.

That is not entirely true.
A GET request has al it's values in the requested url in the protocol.
This means it's limited in size. A POST request has the POST values in the
body of the request. This means a difference in formatting the data.

No - there is a difference in how its transfered but there are several
syntactic and semantic differences.

Yes - although:
1) it's nothing to do with PHP
2) it won't work everywhere

If you post (pvar=3) to a url with a query (http://www.example.com/?
gvar=splodge) the relevant variables will appear in the _POST and _GET
arrays. All variables will appear in _REQUEST.

If you look at you javascript which actualy makes the request it will
typically decide at runtime whether to create a document or use
xmlhttprequest.

If it does something like this:

requestor = document.implementation.createDocument(blah,blah,blah);

then you can't (AFAIK) post.

if on the other hand it does this:

requestor = new XMLHttpRequest(); - for a sensible browser
requestor = new ActiveXObject("Microsoft.XMLHTTP"); - for MSIE
requester.open("GET"...

just amend the javascript to something like:
requestor.open("POST",URL,async);
reqestor.setRequestHeader('Content-type','application/x-www-form-
urlencoded');
(if your using async, set a callback)
requestor.send('posted=something&othervar=4');

IIRC the HTTP protocol does not limit the size or a URL - but MSIE
does (to about 2kb)
