WeOnlyDo! COM Http DLX Client ActiveX Control Introduction

General information
WeOnlyDo Software's wodHttpDLX is a HTTP client ActiveX control that provides easy, both high and low level access to the complete HTTP protocol. It's primary purpose is to retrieve document and other resources from the WEB. It was designed to be as programmer-friendly as possible. You will find it can be fully automated to get you requested resource, but also can be used by advanced programmers under complete control from your code.

Usage model
Default behavior of wodHttpDLX is to do as much as possible to get resource you request - it will automatically connect, try to pass through proxy server (if set), try to authenticate with both proxy and the server, follow redirections,..., until it finally grabs requested resource, and then it will disconnect. If the problem occurs during this automation, you will receive notification about failure, so you can request the resource again using different information provided. Or.. You can use wodHttpDLX to manually connect to the server, send request, check received response, parse received data by yourself - almost all aspect of HTTP protocol is covered by wodHttpDLX. You can have full control over it's behavior if needed - it's all up to you to decide which path you will go.
