Hi in my development machine I want to completely turn off caching (all types) for php. No matter what I try IIS 7 is still caching and it really drives me crazy!
OK, this may be a late response, but i had a similar problem, that it turns out was caused by a PHP accelerator called wincache.
just comment out this line in php.ini [PHP_WINCACHE] ;extension=php_wincache.dll
Check if you have the below mentioned entry in your applicationHost.config file.
Change the true to false and you should be good..
Click on the Web Site -> Output Caching click on Edit Feature Settings... uncheck Enable cache and Enable kernel cache
