How the HTTP API works

All functions in the HTTP API are methods of the MMHttp object. Most of these functions take a URL as an argument, and most return an object. The default port for URL arguments is 80. To specify a port other than 80, append a colon and the port number to the URL, as shown in the following example:

 MMHttp.getText("http://www.myserver.com:8025"); 

For functions that return an object, the object has two properties: statusCode and data.

The statusCode property indicates the status of the operation; possible values include, but are not limited to, the following values:

• 200: Status OK

• 400: Unintelligible request

• 404: Requested URL not found

• 405: Server does not support requested method

• 500: Unknown server error

• 503: Server capacity reached

For a comprehensive list of status codes for your server, check with your Internet service provider or system administrator.

The value of the data property varies according to the function; possible values are specified in the individual function listings.

Functions that return an object also have a callback version. Callback functions let other functions execute while the web server processes an HTTP request. This capability is useful if you are making multiple HTTP requests from Dreamweaver. The callback version of a function passes its ID and return value directly to the function that is specified as its first argument.
