WebClient provides a simple yet complete HTTP client implementation.

To view the documentation evaluate:

	HelpBrowser openOn: WebClientHelp.

The simplest form to use WebClient is by one of its convenience APIs:

	WebClient httpGet: 'http://www.squeak.org/'.
	WebClient httpPost: 'http://www.squeak.org/' content:'Hello Squeak' type: 'text/plain'.

.....

 WebClient httpGet: 'http://wiki.squeak.org/squeak/1586'

The answer object is a WebResponse instance.

 WebResponse(HTTP/1.1 200 OK
 server: nginx/1.14.2
 date: Sat, 16 Mar 2019 12:19:57 GMT
 content-type: text/html; charset=iso-8859-1
 transfer-encoding: chunked
 connection: keep-alive
 expires: 0
 cache-control: no-cache
 pragma: no-cache
 x-clacks-overhead: GNU Terry Pratchett
 content-encoding: gzip
 )

WebClient uses HTTPSocket as the request handler, see method #registerHttpSocketRequestHandler.
WebClient uses the WebUtils class.

WebClient is included in the base image since April 2015 and thus with Squeak 4.6.
It was first released in May 2010: WebClient and WebServer 1.0 for Squeak 4.1.
So the WebClient core package includes as well a simple WebServer.
The package also has been ported to Cuis: https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev/blob/master/Packages/Features/WebClient.pck.st.

Example:
