AJAX - http.send(null)

[afrinspray]

I get this error everytime I finish an AJAX post with http.send(null):

Error: uncaught exception: [Exception... "Component returned failure
code: 0x80004005 (NS_ERROR_FAILURE) [nsIXMLHttpRequest.send]"
nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: [file
name here] :: getReplyWindow :: line 62" data: no]

Is it necessary to follow up the final http.send with http.send(null)?

Thanks,
Mike

try this instead:

http.send("");

Nope I still get it. When I send http.send(null) on a get, everything
works fine- just not when posting after sending the post parameters.
Are you only allowed to do one http.send() command per state change? I
mean, there's these:
0: Uninitialized
1: Loading
2: Loaded
3: Interactive
4: Finished

After the first send, it just goes into state 4, huh?

You are not making any sense. XMLHTTPRequest::send() can only be called
once-in-a-row reliably.

The meaning of this is entirely different than passing `null',
and it does not have anything to do with the exception:

Please get informed before you try to provide any advice.

Dear Thomas 'PointedEars',

I was asking why send can't be called more than once...

Also, Rob was just trying to help. Stop breeding negativity on the
newsgroups.

Thanks,
Mike

And /I/ provided that answer.

Also, Rob was just trying to help.

But he did not. He posted some wild assumption of his.

Stop breeding negativity on the newsgroups.

Go away. Thanks.

Is hardly an answer... how does that explain why?

Alright after wasting a half hour of my life I finally understand the
send method of xmlhttprequest. God bless you PointedEars.

BTW nice nickname! Must suck being a vampire. Also I might just have
to change my name to afrospray.

You needed _half an hour_(!) to understand the connection between

Alright fine. I didn't even click the link. But you still have a
retarded name.
