Everything's as requested.

Well I'll take what I can get.

Don't tell me who to do!

We could have our servers in this case we'll use the Hipmunk example.

the IPP request failed for an unknown reason

We can talk about users and how much trouble they cause us.

The IPP request failed for an unknown reason.

We'll call this get_cords, and this is the first function we're going to be implementing.

And so the industry standard is don't cache POST requests.

But since Mr. Meegar has been enhanced he'll give off a stronger signal than your average Joe.

This is where XMLHttPRequest come in.

Any requests?

GET parameters are included in the URL and POST parameters are included in the body.

So first we'll go to our Editor and we'll switch these lines around again so we can see the actual request.

POST requests, on the other hand, are okay to change the Server.

And POST parameters are used for making updates to the Server.

Is it after the HTTP request headers?

Okay quick quiz

That's kind of a side effect of the fact that we're not printing the actual request.

Now I can go back to my browser and see this is immediately working.

Did you see garbage?

This is a piece of music he specially requested. Start the tape, please Holly.

And now we can go back and view this in our browser.

This will save us from having to call get_page twice. Get_page is fairly expensive.

Next, we specify the onload parameter, which is a function that we define that gets called once the server responds to our request.

Output tab.

One is too much load, as in a database that's just doing too much work.

But do you remember from our first lesson when we talked about

And then the time the message was left.

Come on down. For, uh, encores I do requests, so I'm afraid you're just gonna have to wing it.

If somebody requested Chopsticks you'd ask for the sheet music.

We'll be talking about it in Unit 6,

It was not.

The methods of this class will handle HTP requests.

If you don't specify method at all, it defaults to get, and that's what we've been seeing.

I can't remember a night when I didn't get at least 3 requests for it.

Their servers are probably on fire, because it's Twitter.

In our cases, we're pretty much always going to want to use GET. Second, we specify the URL to call out to.

Alright, now let's try creating our own XML HTTP request.

This list doesn't mean anything. They're just requests.

So just be thoughtful before you suggest something too outlandish.

When we handle unit2 welcome, we come to this handler here, welcome.

I'll import the Web App module and then define a handler, which will handle the requests from the application.

And then I'm going to use different variables to test their validity, and I'll add those now.

These databases were really, really hot and had no real time requests.
