The Timeless WorldWide Unique Number (TWUN) this is a research onwards Twunning, a continuening, based on WUN, with this different : a WUN is used to Keep an eye on Session Pools, but a Twun is about creating a Timeless Server Side Database of the unique user. While digging into http headers document, i saw something called etags. transfered to the server by " If-none-match" did i understand it correctly, that this means, that the browser hands over a tag, the server checks it, and based on that the server responds by saying it aint't modified, or for example, just transfers the file ? So, what will happen if i create a homebrewn etag routine, on a special location ,say http://somehost:someport/someuin.htm and starts counting with aaaaa:0001 for the first person to ask this adres. Then return a aaaaa:0002 for the second person, browser 1 comes back another day, sends the "if-none-match aaaaa:0001" inside's it's get header Gees, thinks the server, welcome aboard User , you 'f been here :o), then smashes the Twun routines, checks the user in his database, addes the Twun to the Wun , and starts logging the Twun in front of the Logbase. and bravely response a " Not Modified, etag =aaaaa:0001" to the user. ---- I don't know if it will work, or can work, problems with proxy will atleast popup's with Twunning, and maybe i'm seeying five things wrong atleast, but hey, it looks funny annyway :o) Any Comment, Or Dis-Comment is welcome.. -- Reinder Kraaij
