I'm not quite sure I understand you, Stevan. What is the URL that you're putting ?flush=1 on the end of? Is this after a successful installation?
?flush=1 clears out SilverStripe's own cache of compiled templates and file-manifest information. It doesn't clear the browser cache or anything.
My problem is that ?flush=1 does not delete CMS (those precompiled templates) cache... So i have problems when changing stuff... Maybe it is windows problem...
Is it enough to delete system temp directory to force CMS to recompile templates?
You have to put ?flush=1 on the URL that actually makes use of the template in question.
However, as you suggest, clearing out the temp folder will force SilverStripe to re-build everything.
On a hosting solution with limited access (basic FTP) I ran into trouble doing releases as the cache would kind of screw things up when new templates where released, especially in conjunction with included files, stylesheets etc.
The solution I found was to put a directory called 'silverstripe-cache' with write access from web server in the home directory where you'll also find 'mysite', 'sapphire' etc.
Silverstripe will create cache there, which you can then delete using a client such as lftp when doing a release.
