Description:

-- Hands-down the easiest connector to deploy for IIS to Tomcat connectivity -- ;o) Simply download, unblock, run setup.

This is the modern method of connecting IIS and Apache Tomcat. Most likely to use a Railo / JSP driven backend.
The BonCode AJP (Apache JServ Protocol version 1.3) Connector uses already existing pathways to connect to Apache Tomcat.
The AJP implementation is generic and will work to connect IIS with any AJP server such as Jboss, web-methods, Jetty etc.
In general it is a preference question how you connect IIS to Tomcat, though, there are several advantages with the BonCode connector vs the old ISAPI connector:
•   no ISAPI code, IIS6 vestiges or backward compatibility elements needed
•   does not block or hinder IIS functionality or slows unrelated requests
•   all managed code for IIS7 using the modern extensibility framework
•   works on IIS5.1, IIS6 and IIS7, IIS7.5, IIS8 (Windows XP through Windows 8)
•   speed, throughput, and stability improvements
•   configuration in IIS UI
•   no virtual directories and virtual mappings needed
•   configuration can be inherited to sub-paths and virtual sites
•   easy install/uninstall
•   support partial stream sending to browser (automatic flushing) with faster response to client
•   support both 32/64 bit of Windows with same process and files
•   transfer of all request headers
•   build-in simple-security for web-administration pages (Tomcat, Railo, OpenBD, ColdFusion)
•   IP6 support
•   Additional HTTP headers data is passed to Tomcat servlet container (previously unavailable)
•   Improved transfer of SSL data to Tomcat servlet container
•   Support improved translation of load balancer headers to determine correct client IP
•   Support client fingerprint mechanism for use with safer sessions
•   Support for Adobe Coldfusion 10 AJP dialect
•   Support for Railo and OpenBD CFML Engines
•   Support for alternate Path-Info header transmission via AJP

If you were using a proxy or URL rewrite engine you would also benefit from:
•   Fully integrated SSL to Servlet container
•   Tomcat threading awareness (will not overload Tomcat and drop connections unnecessarily)
•   Your servlets and scripts will receive correct HTTP header/URL/IP information for processing
•   reduced traffic and processing on both IIS and tomcat sides
•   allows you to connect to multiple tomcat instances from within one IIS site without interfering with ISAPI connector, e.g. Shibboleth and ColdFusion 10/Railo

Version 1.0rc Updates:
* Add: installer deploy in GAC mode
* Add: installer configure tomcat server.xml if on same server

* Add: setting to show suppressed headers (AllowEmptyHeaders). The connector skips headers that do not have data to speed processing. Set to true to send empty headers as well.
* Add: setting to send path info in alternate http header (PathInfoHeader). This is to bypass tomcat bug with AJP path-info transfer.
* Fix: Remove default for ResolveRemoteAddrFrom (HTTP_X_FORWARDED_FOR). Will now need to be explicitly set to be enabled.

* Fix: AJP protocol header server and port designations send to servlet container were incorrect when IIS and tomcat were remoted.
* Add: HTTP header Blacklist and Whitelist options in settings file

Version 0.9.2 Updates:
* Fix: Issues with UTF-8 conversion from double byte regions
* Fix: Forced Disconnect mode was not enabled when MaxConnections was set to zero, references to old connections would be maintained unnecessarily
* Add: Automatic release of all connection when settings file is changed
