Php Website Enhancement - Cache Dynamically Created Pages

Currently on the website, a website search is run on the index page and is passed over to the [login to view URL] page with a few php scripts being included on the page. The total time to parse the page is about 30 seconds. The same search can be run from the [login to view URL] page plus one additional search. The pages created each have their own url through a htaccess rewrite. The rewrite looks like this [login to view URL] Scope of work 1: I need the pages to be cached as an html page to either a msql database or to a cache file. The Database would be a better solution. I would like the cache to stay for two weeks before the script is run again. The script should run again only when the person performs the same search and the cached file is out of date. The url of the cached file should be the same as the url that is dynamically created when the user performs a search. 2: Right know there are two columns and in both the columns are banners. Inside one of the columns I want a list of the 25 most recent searches performed. The list should be formatted with header tags and should link to the url of the search which would end up being the cached html file. The list should not have the same item listed twice with in it. 3: At the bottom of the page there is a link back java script code that the user can embed on their website displaying their pr rating. The backlink only goes to back to the website. I need that changed to link back to the page of the search (the cached file). That function is on the [login to view URL] file. The included files are for reference only. If more files are needed to bid the project please let me know. I will provide the database. I will send the most current files at the start of the job.
