I've extended the DotText engine again, by writing a plug-in to support emitting of Monthly and Daily RSS and Atom feeds.

This is integrated into DotText by adding 4 HttpHandlers into web.config, as seen below.
      <HttpHandler pattern="^(?:/(\w|\s|\.)+/archive/\d{4}/\d{1,2}/\d{1,2}\.aspx/rss)$" type="Dottext.Extensions.DayRssHandler, Dottext.Extensions" handlerType="Direct"/>
      <HttpHandler pattern="^(?:/(\w|\s|\.)+/archive/\d{4}/\d{1,2}/\d{1,2}\.aspx/atom)$" type="Dottext.Extensions.DayAtomHandler, Dottext.Extensions" handlerType="Direct"/>
      <HttpHandler pattern="^(?:/(\w|\s|\.)+/archive/\d{4}/\d{1,2}.aspx/rss)$" type="Dottext.Extensions.MonthRssHandler, Dottext.Extensions" handlerType="Direct"/>
      <HttpHandler pattern="^(?:/(\w|\s|\.)+/archive/\d{4}/\d{1,2}.aspx/atom)$" type="Dottext.Extensions.MonthAtomHandler, Dottext.Extensions" handlerType="Direct"/>

The Dottext.Extensions.dll assembly written in C# enables examples of the following:
In addition, another Dottext assembly written in Delphi.NET enables all RSS feeds to emit updateFrequency, updatePeriod, updateBase and ttl elements, hence ensuring that if your syndicated reader supports it, it'll be more efficient.
