For more ## information, please see MoinMaster:MoinPagesEditorGroup. ##master-page:Unknown-Page ##master-date:Unknown-Date ##acl MoinPagesEditorGroup:read,write,delete,revert All:read #format wiki #language en == Quick Start == To quickly begin with the beta you need 4 jar files that can be downloaded from [http://www.apache.org/dist/httpcomponents/httpclient/binary/httpcomponents-client-4.0-beta2-bin-with-dependencies.zip] A good place to learn how to use the API quickly is to see the code in action. Can see good samples that have several everyday tasks automated. They are included in the jars at download page [http://hc.apache.org/downloads.cgi] . Good starter material is also at [http://wiki.apache.org/HttpComponents/GuidedTourOfHttpCore] Remember Http Components are not a complete browser. Importantly it lacks parsers, layout engine, UI, cache, renderer and a JavaScript engine. To learn the scope of these components see [http://hc.apache.org/httpcomponents-client/primer.html] {{{ Note: this guide is not complete and contributions are welcome.
