Remote-Preview

Remote Preview works by making an ajax call every 1100ms to check if the url in the 'url.txt' file changed. If it did, the script will then change the src attribute of the iframe and load a new page into it. If there's no changes, the script will just keep polling the url.txt until something changes. Remote Preview allows very fast previewing of different URL's to check for possible layout problems, which can then be debugged using various other tools depending on the platform where they occur.
