Discussion Page for IIS
We need to create a few more pages to this section -- let's get started!
If you think the following is valid for a page, add it to the main trunk. Here are the ideas for pages that have been discussed or that I thought of.
- IIS-compatible extensions list
- How to update your extension to make it IIS-compatible
- IIS versions and what, if any, differences there are vis-a-vis Joomla compatibility
- IIS and Joomla 3.0
