User Agents are objects which wrap URLs which are known as the "location" or the "context." They fetch and cache the index from their location, then query the index's meta-data for links to new URLs. A new Agent is created to wrap the matching URL. It maintains a back-reference to its parent, and is known as having a "relative context."

Fetching the index is known as "resolution," and is triggered by the first resolve() or dispatch() call. If the Agent is relative, its parent may need resolution first, so the full ancestry is triggered to resolve in the process. The unresolve() function will clear the cache of the Agent so that it will re-resolve on its next dispatch.

It's useful for me to think of Agents as database cursors.

RUSH (sorry bri, I have to... for the Getty) has a syntax for specifying an Agent in its requests:

  myagent> GET foobar-generator

Plugin-driven Web Applications

A design overview

Read first: In-Application Sandboxing with Web Workers. It explains the rationale behind using Web Workers.
And: Communicating with Workers using HTTP. It explains the rationale for choosing HTTP for messaging.

The TL;DR:

• Web Workers behave as Web services in a local HTTP namespace

Server Objects, and How VMs are Bridged

Every VM has multiple server objects

• they make up the httpl:// namespace
• may be functions or objects with a handleLocalRequest method

"Bridge" servers wrap the postMessage interfaces

• a request to httpl://the-worker is postMessageed

var myitems = [];
testserver.route('/protocol/crud-coll')
  .link({ href: '/protocol/crud-coll', rel: 'self', title: 'My Collection' })
  .protocol('stdrel.com/crud-coll', {
    itemUrl: '/protocol/crud-coll/{id}',
    validate: function(item, req, res) {
      var errors = {};
      if (!item.fname) errors.fname = 'Required.';
      if (!item.lname) errors.lname = 'Required.';
      return errors;
