Dear Mr. Kehren,
First, thanks for the very informative article.
As long as our first question is concerned, we tested it and it worked. Also, for our second question, cross (Kentico) site copy & paste is supported.
Regarding our third question, we still don't have a definite answer, so let me elaborate more on our multi-site project.
As I mentioned, we need to develop three web sites in the same Kentico MVC instance. All three web sites share the same page types (except for a small number of pages e.g. the homepage page type) and only one of them has additional page types that uses exclusively.
Taking into account the article's proposed application configurations, due to the large quantity of page type sharing, there is no need to have different physical (MVC) application folders (one for each web site), but a single physical (MVC) application folder for all three web sites will suffice.
Also note that in terms of (MVC) routing, we have developed a mechanism that automatically forwards each page request to a specific controller based on the page type's ClassName.
So, we may have a working instance either by using a single IIS Web Site with three bindings or by using three IIS Web Sites with a single binding. In both cases all IIS Web Sites point to the same MVC application folder.
Which configuration is best for our case?
Thanks in advance and Merry Christmas,
