Bookmark server

I am planning on writing a "bookmark server" in php. The idea is I will have a database that stores all my internet favorites on a web server some where, so if I am doing some web browsing away from home and find a site I want to save, I can go to my bookmark server and save the url there. Now for the part I can't figure out an easy way to do. I want to have it so if I am looking at a page I want to save I can type in a nice short url for my bookmark server and it will some how be able to know where I just came from and have the form fields for URL and description already filled in for me. Then I just have to tell it what category to save the bookmark in. First I thought the _SERVER["HTTP_REFERER"] variable, but that only works if you click on a link and since every web page I want to save won't have a link to my bookmark server that won't work. Then I thought I could use the history array with javascript, but that only works if your script is signed and I don't want to go there. So now I am out of ideas and was wondering if anyone here had any. Chris W http://thewishzone.com:8086/
