WebSockets - An Introduction

WebSockets is a modern HTML5 standard which makes communication between client and server a lot more simpler than ever. We are all familiar with the technology of sockets. Sockets have been fundamental to network communication for a long time but usually the communication over the browser has been restricted. The general restrictions

• The server used to have a permanent listener while the client (aka browser) was not designated any fixed listener for a more long term connection. Hence, every communication was restricted to the client demanding and the server responding.
• This meant that unless the client requested for a particular resource, the server was unable to push such a resource to the client.
• This was detrimental since the client is then forced to check with the server at regular intervals. This meant a lot of libraries focused on optimizing asynchronous calls and identifying the response of asynchronous calls. Notably t

ETags: a pretty sweet feature of HTTP 1.1

HTTP caching review

HTTP provides two ways for servers to control client-side caching of page components:

• freshness may be based on a date or a token whose meaning is app-specific
• whether or not the client needs to confirm the cached version is up-to-date with the server

This breaks down as follows:

• Cache locally and don't check before using.

formátování <fieldset> a <legend> je opravdu vojeb. veškerá řešení, 
která jsem našel vyžadovala přidat do kódu nějaké pomocné <div>y nebo 
<span>y. takové řešení mi ale nevyhovuje

nakonec jsem dospěl k tomuto. vypadá na pixel stejně ve všech novějších 
prohlížečích včetně IE7. v IE6 a starších (bez selektorů + a >) nefunguje
