MSDN [msdn2.microsoft.com] - The primary mission of ATL Server is to provide support for responding to HTTP requests, but ATL Server also provides client-side support. This functionality allows launching of HTTP requests and handles receiving the resulting HTTP responses. With the exception of basic HTTP response header parsing, the ATL Server HTTP client support does not perform any HTTP response parsing or rendering.
MSDN [msdn2.microsoft.com] - The Microsoft CryptoAPI allows developers to build cryptographic security into their applications by providing a flexible set of functions to encrypt or digitally sign data.
Microsofts implementation of Web Distributed Authoring and Versioning (WebDAV), which is in XP and all future version of windows.
Example: "Microsoft URL Control - 6.00.8877"
This is one of Microsoft's generic com library for web requests which Visual Basic and any other language which can use com objects can access. And documentation for changing the default User-Agent header is lacking when I last checked, so most often never changed.
Example: "Mozilla/4.0 (compatible; MSIE 6.0; MS Web Services Client Protocol 2.0.50727.42)"
This is the default User-Agent for webservices connecting code generated by the default tools in Dot.net. And can easily be changed but often is forgoten about in the rush to finish off the webservice linking software.
