Wildcard mapping (IIS 5-6.1)

On IIS 5 to IIS 6.1 wildcard mapping can be enabled to support “extensionless urls” (no ending .aspx on each page address). Wilcard mapping is an IIS feature that enables requests to all types of resources to pass through managed ASP.NET code. This allows N2 CMS to serve pages for pages not ending with .aspx. This is configured slightly differently depending on IIS version. Try searching and pick the version you’re using:

Visual Studio Development

  • Visual Studio 2012 is recommended for site development with N2CMS.
  • Visual Studio Express can also be used.

Visual Studio 2012 project files are included in the N2CMS source tree.

Shared Hosting

Some users report no problems running in shared hosting under medium trust, others have had problems. N2CMS has been tested on unmodified medium trust. It’s recommended you ask the hosting provider before you buy a long-term plan. Note that N2CMS can be somewhat RAM intensive, and requires a minimum of 64 MB of RAM dedicated to your website. More RAM may be needed depending on the plugins you require or the amount of traffic your website receives. Plug-ins such as site search can also increase the memory requirement.
