So for mostly load and processing time I want to edit the html directly in the data tables pages. Basically I append the data to the page_text of the selected pages and then recycle the application pool to force the cache to refresh.

This works except I think I'm getting caught up on a security feature, the html ends up being change to having the htmlentities, so < turns into &lt; which of course makes the entire page just display the html source.

Is there anything I can do to do this?

I really can't write an on demand plugin due to the time it takes to gather and process the information. I thought about dumping the data to html files on disk and writing a plugin to read them from a basic web service but I didn't really want to set up anything more complex than I had to and appending to the html in the database is the easiest and fastest.
