[postgis-devel] PostGISonline.org is online :-)

Mon Mar 8 13:20:57 PST 2010

There seems to be some problem when using both iframes and AJAX in firefox. Sometimes, not always the AJAX request never get sent from the browser.

That's why the site has been acting strangely this evening when I have tried to figure out what is happening.

But now it is restored because I have to do a bigger rewriting I think so I shall set everything up locally.

Does anyone happen to knoe anything about this problem here?

There are continuous integration services you could install thatare smart enough to check SVN (the one I'm familiar with is CruiseControl, butthere are others) and build when necessary.  It also would not be too hardto have your script just look at the last checkin time in SVN and only run ifthere's been a change in the last day, hour, 5 minutes, however often youdecide to check.

The tutorial thing works and makes it possible to just passthe tutorial-utl as a querystring, but I have disabled it now because I don'tknow how to handle the security issues.
