batchhttp provides parallel fetching of HTTP resources through MIME multipart encoding.

This package's BatchClient applies standard MIME multipart encoding to HTTP messages, providing a standards-conservant technique for making parallelizable HTTP requests over a single proxy connection.

To make a batch request, open a new request on a BatchClient instance and add your subrequests, along with callbacks that will receive the subresponses. Once all parallelized requests are added, complete the request; the request is made and the batched subresponses are provided to your callbacks.

This is an implementation of the draft specification for batch HTTP request processing available at:

https://github.com/apparentlymart/http-batch-specs/blob/master/batchhttp.xml

This specification is now largely abandoned and this library is now primarily of historical interest only.
