RequestCore is a lightweight cURL-based HTTP request/response class that leverages MultiCurl for parallel requests.
RequestCore was written as a replacement for PEAR HTTP_Request. While PEAR HTTP_Request is full-featured and heavy, RequestCore features only the essentials and is very lightweight. It also leverages the batch request support in cURL's curl_multi_exec() to enable multi-threaded requests that fire in parallel.
