Clear Safari 5.1 Cache

When working on projects – I generally need to refresh pages multiple times (to see CSS changes, etc). I generally work with my browser’s cache disabled (Develop Menu > Disable Caches in Safari) but I noticed that simply pressing the return button on a page/site in Safari 5.1 did not work. It was driving me absolutely crazy. I then decided to click on the reload button in the address bar (far rich side) (looks like a circular arrow). This actually reloaded the page properly. I am not really sure why simply pressing return (to reload the page) did not work – especially with the cache “disabled” – but by clicking on the reload icon works to display the page without any cache issues. I hope this helps someone else!
