Use desktop webinspector to clear cache in mobile safari?

I'm using Safari 11.1 on a macbook, and using Web Inspector connected to an iPhone with iOs 11.2.6.

From the Web Inspector, if I use the key board short cut: OPTION + COMMAND + R, it both clears the cache and reloads the page.

I came across this issue with safari 11.1, and the answer was really simple. There is actually a button on the right top corner of the network tab to disable caching when debugging. I thought about leaving this just in case someone else miss the button just like I did. ( the one in blue )

You can use Cmd + Option + R while in the developer tools web inspector to force mobile safari to reload its cache.

I had another problem which was that Fiddler also has a cache. I also had to clear that as I was running the iPad through the fiddler proxy.

Once I cleared the fiddler cache, and then used Cmd + Option + R, I could see the iPad requesting and receiving the new files.
