Stop caching my pages during local development

Question

I've been working on a set of web development projects over the last few months, and have encountered the following problem: no matter what I do, every browser I have caches every page I load, which makes it impossible to know if an edit hasn't worked or if I'm viewing a cached version. I've tried Google Chrome, in Incognito Mode and with the Developer Tools open. I've tried Mozilla Firefox, gone into about:config and disabled every single kind of caching I could find. I've tried Safari Private Mode. I've cleared my cache several times on each browser. I've tried adding headers that should prevent caching. I've tried appending a random number to the URL so the URL changes every time I open the page; I am still getting cached versions of the page somehow. Does anyone have any tips, in any of these browsers, to make the constant caching of pages stop? I'm running Mac OS X Mavericks, if that helps.

Are you using MAMP?

This happened to me, and had to do with a newer version of MAMP. In your MAMP Dir go to : /bin/php/php5.5.3/conf/php.ini And comment the Opcahe lines:

[OPcache]
;zend_extension="/Applications/MAMP/bin/php/php5.5.3/lib/php/extensions/no-debug-non-zts-20121212/opcache.so"
;  opcache.memory_consumption=128
;  opcache.interned_strings_buffer=8
;  opcache.max_accelerated_files=4000
;  opcache.revalidate_freq=60
;  opcache.fast_shutdown=1
;  opcache.enable_cli=1
