httprl 6.x-1.4

Note:
Be sure to flush the menu cache if you wish to access the Configuration page.

Bugs Fixed:
#1420080: Settings form not shown
#1420488: Remove more D6 leftovers that will break in D8
#1419728: Use drupal_convert_to_utf8() for UTF8 conversion
#1420440: Wrong placeholders used in translatable strings of httprl_requirements()
#1420496: HTTP tests are failing
#1419686: Remove invalid referrer
#1420472: D7 upgrade: exit; -> drupal_exit(); leftovers
#1419672: Responds object incomplete / inconsistent
#1420092: httprl_lock_release() not upgraded to D7
#1420084: Status page shows warning as it's using IPv6 and not IPv4 address
#1420104: Logic is broken with redirects

New Features:
#1268096: Implement a rate limiter
#1419744: Exit processing in httprl_send_request() after specified page request run time
#1426886: Allow HTTPRL to operate at the database bootstrap level.
#1426854: Enforce Range headers on the client side

Notes on the new features:
- domain_connections: Maximum number of simultaneous connections to a given domain name. Default is 8.
- global_connections: Maximum number of simultaneous connections that can be open on the server. Default is 128.
- global_timeout: A float representing the maximum number of seconds the function call may take. If a timeout occurs, the error code is set to the HTTP_FUNCTION_TIMEOUT constant. Default is 120 seconds.

Added new documentation for headers that can be sent to the server:
- For POST: 'Content-Type' => 'application/x-www-form-urlencoded',
- Limit number of bytes server sends back: 'Range' => 'bytes=0-1024',
- Let server know where request came from: 'Referer' => 'example.com',
- Content-Types that are acceptable: 'Accept' => 'text/plain',
- Send Cookies: 'Cookie' => 'key1=value1; key2=value2;',
- Skip the cache: 'Cache-Control' => 'no-cache',
- Skip the cache: 'Pragma' => 'no-cache',

HTTPRL can safely be ran at the DB bootstrap level now.

require_once './includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_DATABASE);

$result = db_query("SELECT filename FROM {system} WHERE name = '%s'", 'httprl');
if (!empty($result)) {
  $row = db_fetch_array($result);
  if (!empty($row['filename'])) {
    require_once './' . $row['filename'];
  }
}

// Can now safely use all HTTPRL functions except for httprl_menu().
