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

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

Any requests?

Everything's as requested.

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

Don't tell me who to do!

Well I'll take what I can get.

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

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

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

Did you see garbage?

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

Is it after the HTTP request headers?

Okay quick quiz

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

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

CA You're peeking.

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

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

And then the time the message was left.

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

We'll be talking about it in Unit 6,

We'll do so aha!

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.

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

It was not.

Output tab.

So just be thoughtful before you suggest something too outlandish.

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

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

He can seat, throughout the year, he can seat 8,000 people.

Networks are all about abstraction.

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

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

I didn't request you to do that.

Lemon tree, very pretty.

Okay, so we add the post function.

We don't want to use their IP. We want to use any IP. That's the URL we'll be requesting.

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

I learned how to do this just by looking in the App Engine docs.

Returns the output of the command if successful otherwise returns FALSE.

Nothing magical there.

Another difference is that GET parameters are generally okay to cache.
