/** File: strophe.js
* A JavaScript library for XMPP BOSH/XMPP over Websocket.

* This is the JavaScript version of the Strophe library. Since JavaScript

* information on BOSH can be found in XEP 124.
*
* This version of Strophe also works with WebSockets.
* For more information on XMPP-over WebSocket see this RFC:
* http://tools.ietf.org/html/rfc7395

*
* To make Strophe connect to the current host you can leave out the protocol
* and host part and just pass the path, e.g.
*
* > var conn = new Strophe.Connection("/http-bind/");
*
* WebSocket options:
*
* If you want to connect to the current host with a WebSocket connection you
* can tell Strophe to use WebSockets through a "protocol" attribute in the
* optional options parameter. Valid values are "ws" for WebSocket and "wss"
* for Secure WebSocket.
* So to connect to "wss://CURRENT_HOSTNAME/xmpp-websocket" you would call
*
* > var conn = new Strophe.Connection("/xmpp-websocket/", {protocol: "wss"});
*
* Note that relative URLs _NOT_ starting with a "/" will also include the path
* of the current site.
*
* Also because downgrading security is not permitted by browsers, when using
* relative URLs both BOSH and WebSocket connections will use their secure
* variants if the current connection to the site is also secure (https).
*
* BOSH options:
*
* by adding "sync" to the options, you can control if requests will
* be made synchronously or not. The default behaviour is asynchronous.
* If you want to make requests synchronous, make "sync" evaluate to true:
* > var conn = new Strophe.Connection("/http-bind/", {sync: true});
* You can also toggle this on an already established connection:
* > conn.options.sync = true;

* full JIDs. To use this, pass {matchBare: true} as the value of
* options. The default value for matchBare is false.

* with deleteHandler().
*
* Parameters:

* (String) type - The stanza type attribute to match.
* (String) id - The stanza id attribute to match.
