class WP_Http {
/**
* Send a HTTP request to a URI.
* Send an HTTP request to a URI.
*
* The body and headers are part of the arguments. The 'body' argument is for the body and will
* accept either a string or an array. The 'headers' argument should be an array, but a string
* is acceptable. If the 'body' argument is an array, then it will automatically be escaped
* using http_build_query().
*
* The only URI that are supported in the HTTP Transport implementation are the HTTP and HTTPS
* protocols.
*
* The defaults are 'method', 'timeout', 'redirection', 'httpversion', 'blocking' and
* 'user-agent'.
*
* Accepted 'method' values are 'GET', 'POST', and 'HEAD', some transports technically allow
* others, but should not be assumed. The 'timeout' is used to sent how long the connection
* should stay open before failing when no response. 'redirection' is used to track how many
* redirects were taken and used to sent the amount for other transports, but not all transports
* accept setting that value.
*
* The 'httpversion' option is used to sent the HTTP version and accepted values are '1.0', and
* '1.1' and should be a string. The 'user-agent' option is the user-agent and is used to
* replace the default user-agent, which is 'WordPress/WP_Version', where WP_Version is the
* value from $wp_version.
*
* The 'blocking' parameter can be used to specify if the calling code requires the result of
* the HTTP request. If set to false, the request will be sent to the remote server, and
* processing returned to the calling code immediately, the caller will know if the request
* suceeded or failed, but will not receive any response from the remote server.
* Please note: The only URI that are supported in the HTTP Transport implementation
* are the HTTP and HTTPS protocols.

* @type array $cookies List of cookies to send with the request. Default empty array.

* Default false.
* @type bool $decompress Whether to decompress a compressed response. If set to false and
* compressed content is returned in the response anyway, it will
* need to be separately decompressed. Default true.
* @type bool $sslverify Whether to verify SSL for the request. Default true.
* @type string sslcertificates Absolute path to an SSL certificate .crt file.
