Enfold Proxy is a lightweight IIS plugin  that lets you manage Plone sites more easily and improve cache performance.  It includes an  easy-to-use wysiwig configuration tool and supports  all recent Vista versions.  Benefits include: 

  • Improves Web client response time and dramatically reduces server load by caching processor-intensive pages locally on your IIS server  (note:  Enfold Proxy works best when your Plone server uses  a  Plone caching product. )
  • Simplifies the process of associating Plone sites with IIS sites.
  • Simplifies the process of integrating Plone  and non-Plone content on the same domain or host.
  • Makes it possible for IIS to handle single sign on with Windows domain users .
  • Maintains and supports security via Secure Sockets Layer (SSL) between your Web and applications servers.
  • Supports load balancing with multiple Zope clients to provide extra reliability in the event one Zope client goes offline. These Zope clients can be on Windows or Unix machines.
  • Provides documentation, tips and examples for getting IIS to handle your Plone site(s).
  • Professional support for the entire Windows platform line.  Windows 2000, XP, 2003, Vista, and Windows 2008.
  • 64 bit platform support now available for Windows XP, Vista and Windows 2008.

Change log

Version 4.5 (October, 2008)

  • The cache is now far more RFC compliant and returns all headers from the original request, except set-cookie. Increased RFC compliance makes it easier for Enfold Proxy to work with existing caching infrastructure and tools.
  • Natively runs as a 64 bit application within Internet Information Server 7 (IIS 7).
  • Official support for Vista 32 bit and Vista 64 bit.
  • All URLs are now correctly quoted and utf8-encoded URLs are supported. (Note: this may not be supported by the backend Zope/Plone server).
  • A new setting for the log files (called the Headers log level) makes it easier to read HTTP headers and verify that caching is taking place.
Other Improvements
  • Slight changes to the Encontrol user interface.
  • Fix a bug that could cause a response with an incorrect content-length to be returned, which may cause some requests to appear to hang.
  • Default cache size is now 100MB (was 10MB) and default max cached item size is now 200k (was 100k)
