I tried something else today and I happened to have Safari's Web Inspector open. I started to see all kinds of MIME error. Sometimes a blank page, sometimes a missing image icon. A few of the errors:

Is static content being served by Active4D? If so, it looks like your ExtensionMap.ini file is missing or corrupt.

Static content is being served by 4D from the web_static folder. Don't know where 4D keeps its extension map.

I was wrong with FireFox - I think. I can't get it to fail. I've also observed this warning on another Active4D site with about the same setup - but I never get a blank page. I was also wrong that these are not reported as errors in web inspector, but warnings. These warning are also present when a page is served. I have not analyzed if there is a pattern between being served and blank - yet.

I watched the tcp packets with tcpdump on the development server. When a page was served blank, there'd only be a couple packets. After about 15 seconds there'd be 3 or 4 more packets. Almost sounds like another keep alive (set to 15 seconds) problem between Safari and 4D. We had a lot of problems trying to upload to Active4D with Safari - gave up and went to a java/php upload. If I can't find anything wrong with the 4D setup, I'll file a Safari bug report.
