Configuration parameters

The HTTP function sends an HTTP request, waits for the response then returns it. The input is a MAP with at least the field url. The response is a MAP with the fields status.code, status.message, headers and content.

The HTTP function can also be used in streaming mode by providing a positive chunk.size argument. In streaming mode, whenever chunk.size bytes are downloaded, a response MAP with the additional field chunk.number is pushed onto the stack and the macro given as chunk.macro argument is being executed. Finally, a last chunk.macro execution is done on a chunk response that has empty content and chunk.number = -1.

The HTTP function makes use of token's capabilities to raise the initial limits per warpscript (set from configurations).

Other configurable options:

HTTP is available since version 2.8.1.
