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

I want to talk today about

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

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

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

Don't tell me who to do!

So just be thoughtful before you suggest something too outlandish.

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

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

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.

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

Did you see garbage?

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

Nothing magical there.

CA You're peeking.

We've also got a url one. Let's see what's in there.

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

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.

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

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

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.

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

Then we have another function for reading a secure cookie.

We'll be talking about it in Unit 6,

I'll try it myself okay we have our form, I click submit, and boom here we are.

Output tab.

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

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

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.

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.

Is it after the HTTP request headers?

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

Okay quick quiz

So we have you, and we have our servers, and you make a request for the form.

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

Let's talk about how they're going to fit into things.
