This is a neat way to mimic content from another site. Your web server can pose as a web browser, visit a web site of your choice, extrapolate content, modify it, and then feed it back to a user on your site. Using a search and replace routine, you can tell the script exactly what to look for and what to put in it s place. A snippet of JavaScript can be instantly removed, or the name of the site can be automatically modified. Don t like the style of the site? It s easy to instruct this script to grab only a portion of the remote site, to change images, and then display it with a header and footer of your choice. Warning: this could be illegal if your intent is to steal content and pose it as your own. You should ask permission of the original site owner before proceeding.
