jQuery/Ajax IE7 - Long requests fail

I have a problem with IE7 regarding an ajax call that is made by jQuery.load function.

Basically the request works in cases where the URL string is not too long, but as soon as the URL gets very large it fails. Doing some debugging on the Ajax call I found this error:

URL: <blanked out security reasons but it's very long>
Content Type: 
Headers size (bytes): 0
Data size (bytes): 0
Total size (bytes): 0
Transferred data size (bytes): 0
Cached data: No
Error result: 0x800c0005
Error constant: INET_E_RESOURCE_NOT_FOUND
Error description: The server or proxy was not found
Extended error result: 0x7a
Extended error description: The data area passed to a system call is too small.

As you can see, it looks like nothing is being sent. Now this only happens on IE7 but not other browsers, with IE8 there is a small delay but still works. The same request works fine when the URL string is relatively small.

Now I need this working on IE7 for compatibility reasons, and I cannot find workarounds for this.

The actual AJAX call is like this:

$("ID").load("url?lotsofparams",callbac func(){}); 

"lotsofparams" can vary, sometimes being small or very large. It's when the string is very large that I get the above error for IE7 only.

Don't put the query string parameters into the the url.

The second parameter of .load() is made just for that. Should be:

$("ID").load("url", {
    foo:     "bar",
    morefoo: "morebar"
},callbac func(){}); 

or you can use $.post()

$.post("url", {
    foo:     "bar",
    morefoo: "morebar"
}, function(data){
   alert(data);
});

Since the .load() will internally use a "POST" request when parsing an object, you might consider to replace it with $.get() if you require a "GET" request.
