Since my Provider upgraded to 4.0.6 some of my scripts don't work as exspected anymore...
I use include() with URL's where the URL's are from the same domain. They fail unpredictable:
example: www.alstereck.de/aecke32001/ingebericht.phtml
With every reload the appearance of the page changes, because the included files change, the rest fails with:

Warning: Failed opening 'http://www.alstereck.de/aeckehead1.html' for inclusion (include_path='') in
/raid/domains/de/a/alstereck/htdocs/www/aecke32001/ingebericht.phtml on line 3

When I include() via URL a file from a non-local server it
works always fine.
If I use this script on a different server with a perhaps
different configuration (even 4.0.6.) it works fine!
