Lately my PHP server (paid host at One.com) has been having a huge delay (approx. 15 minutes) from I change something in my code, to the actual change in the files. When I log in to the FTP, the changes are there, but there is a 15-minutes delay to the change appears in the HTTP. This makes it completely impossible to code anything, as coding often is tweaking one little number until it's perfect. To make it short: I can't wait 15 minutes.
My host says, that it's the X-cache.
Do you know anything I (or my host) can do to solve this?
My host offered me to disable the X-cache, but they said, that there'd be a up to 30 minutes delay from entering the site, to your computer receives the HTML, as the server would have to "dig everything up from root".
Please help me!
