wodHttpDLX
-
Version
1.7.2
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 documents 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.
Includes component to parse HTML files
Since version 1.1.0.2, wodHtmlParser component is
included in wodHttpDLX package free of charge. You can
extract almost any data using this component. For
example, you can easy get pictures from the page (using
one line of code!!), find Google links, escape frames
etc.. Provided samples will teach you on how to do
basic stuff - and you'll see how easy it is!
