Our website has become too popular and the hosting company says that we must install a caching mechanism on index.php. We need this right away so if you cannot get to it immediately please don't bid. As a part of your bid, please let us know how you would solve the problem of high server processor load. Our site is built in php with Smarty Templates. We don't like the fact that it might mess up the statistics reporting. If there is something you can do to keep our stats, please let us know that also. If you can offer a different solution such as move to a dedicated server with your recommended hosting company we will listen to that also.
Install a caching system on the index page so that a new page is not generated every time.
After you are finished, you must write up an explanation of exactly what you did so that this explanation can be passed to our hosting company for approval. (Hostgator)
