[IE程式設計] 了解Urlmon.dll和Wininet.dll

wininet.dll

Caching, History, Cookie Management 

Authentication - Basic, NTLM, Kerberos 

Connections - Both secure (schannel) and non-secure 

Dial-up, Direct, Proxy 

Protocol and HTTP header management 

urlmon.dll

URL Parsing – breaking down URLs into the protocol used (HTTP, HTTPS, FTP, File, Gopher), address, and target. 

GZIP compression/decompression – provides support for GZIP HTTP compression to deflate and inflate data.  IE6 and IE7 handle this slightly differently.  In IE7 this functionality is handled by WinINet. 

Security and Zone Management – Identifies security zones, zone crossings, permissions, etc. 

Asynchronous Pluggable Protocol Filter/Handler – correlates appropriate the protocol to the registered handler (HTTP, HTTPS, MAILTO, FILE, etc.). 

Code Download Management, Install On Demand, and Just-In-Time. 

Forms requests from the URL – creates the outbound data package and hands it off to WININET for transfer. 

MIME (Multipurpose Internet Mail Extension) type management – examines the MIME type for data returned in an HTTP response and correlates that type with a specific handler. For example, URLMON would open a Microsoft Word document (MIME type .doc) with Microsoft Word. If the MIME type is not clear from the response, URLMON is capable of examining the binary data to determine the appropriate MIME type. MIME is described more thoroughly in RFC1521.
