//
// This working example, complete with fully commented code, illustrates one way
// in which this PHP script can be used.
//
// Simple - http://benalman.com/code/projects/php-simple-proxy/examples/simple/
//
// About: Release History
//
// 1.6 - (1/24/2009) Now defaults to JSON mode, which can now be changed to
//       native mode by specifying ?mode=native. Native and JSONP modes are
//       disabled by default because of possible XSS vulnerability issues, but
//       are configurable in the PHP script along with a url validation regex.
// 1.5 - (12/27/2009) Initial release
//
// Topic: GET Parameters
//
// Certain GET (query string) parameters may be passed into ba-simple-proxy.php
// to control its behavior, this is a list of these parameters.
//
//   url - The remote URL resource to fetch. Any GET parameters to be passed
//     through to the remote URL resource must be urlencoded in this parameter.
//   mode - If mode=native, the response will be sent using the same content
//     type and headers that the remote URL resource returned. If omitted, the
//     response will be JSON (or JSONP). <Native requests> and <JSONP requests>
//     are disabled by default, see <Configuration Options> for more information.
//   callback - If specified, the response JSON will be wrapped in this named
//     function call. This parameter and <JSONP requests> are disabled by
//     default, see <Configuration Options> for more information.
//   user_agent - This value will be sent to the remote URL request as the
//     `User-Agent:` HTTP request header. If omitted, the browser user agent
//     will be passed through.
//   send_cookies - If send_cookies=1, all cookies will be forwarded through to
//     the remote URL request.
//   send_session - If send_session=1 and send_cookies=1, the SID cookie will be
//     forwarded through to the remote URL request.
//   full_headers - If a JSON request and full_headers=1, the JSON response will
//     contain detailed header information.
//   full_status - If a JSON request and full_status=1, the JSON response will
//     contain detailed cURL status information, otherwise it will just contain
//     the `http_code` property.
//
// Topic: POST Parameters
//
// All POST parameters are automatically passed through to the remote URL
// request.
//
// Topic: JSON requests
//
// This request will return the contents of the specified url in JSON format.
//
// Request:
//
// > ba-simple-proxy.php?url=http://example.com/
//
// Response:
//
// > { "contents": "<html>...</html>", "headers": {...}, "status": {...} }
//
// JSON object properties:
//
//   contents - (String) The contents of the remote URL resource.
//   headers - (Object) A hash of HTTP headers returned by the remote URL
//     resource.
//   status - (Object) A hash of status codes returned by cURL.
//
// Topic: JSONP requests
//
// This request will return the contents of the specified url in JSONP format
// (but only if $enable_jsonp is enabled in the PHP script).
//
// Request:
//
// > ba-simple-proxy.php?url=http://example.com/&callback=foo
//
// Response:
//
// > foo({ "contents": "<html>...</html>", "headers": {...}, "status": {...} })
//
// JSON object properties:
//
//   contents - (String) The contents of the remote URL resource.
//   headers - (Object) A hash of HTTP headers returned by the remote URL
//     resource.
//   status - (Object) A hash of status codes returned by cURL.
//
// Topic: Native requests
//
// This request will return the contents of the specified url in the format it
// was received in, including the same content-type and other headers (but only
// if $enable_native is enabled in the PHP script).
//
// Request:
//
// > ba-simple-proxy.php?url=http://example.com/&mode=native
//
// Response:
//
// > <html>...</html>
//
// Topic: Notes
//
// * Assumes magic_quotes_gpc = Off in php.ini
//
// Topic: Configuration Options
//
// These variables can be manually edited in the PHP file if necessary.
//
//   $enable_jsonp - Only enable <JSONP requests> if you really need to. If you
//     install this script on the same server as the page you're calling it
//     from, plain JSON will work. Defaults to false.
//   $enable_native - You can enable <Native requests>, but you should only do
//     this if you also whitelist specific URLs using $valid_url_regex, to avoid
//     possible XSS vulnerabilities. Defaults to false.
//   $valid_url_regex - This regex is matched against the url parameter to
//     ensure that it is valid. This setting only needs to be used if either
//     $enable_jsonp or $enable_native are enabled. Defaults to '/.*/' which
//     validates all URLs.
