Hi guys im working on a Project soon to create a shopping cart system and a feature will be send details to a Shared SSL.. so this will be a different server.. as this is a purchaseable piece it will have Private SSL also.

my question is what is the best way to send cart details from one server to other.. safely eleminating hacking etc... or continiously submitting to the other server..

i thopught about sending a veriable accross but its hard to do a random gen veriable from one server to the other and validate it.

does anyone have any ideas?

By only cart details do you mean products they have requested to purchase?

If so, then it doesn't really matter how you do it, just have an order confirmation page on the SSL server to ensure their cart hasn't been changed in the process.

hiya

the Shared server option will have all content sent via form unless using the MSSQL Version, as it will be a serperate server ussually.

but this will be an option.

i had a thought on an idea what do you think on the below idea


i have Server 1 and Server 2

i have a Univeral Salt Code on both servers that match

when submitting from Server 1, i get the Univeral salt code and generate a random value. i then Hash encrypt it (forum style)

and pass the encrypted version along with the random value to Server 2

i then use Server 2 Salt code (same as server 1's one) and use the random value sent via the form and Hash encrypt the server 2 Salt Code with the form Random Value and if the output matchs the form Encrypted Version it was sent From Server 1


the Univeral salt Code for the application will be randomly set on install using FSO to change a value within the ConFig files that hold details that can't be in the Database.

the idea sort of uses Session veriable idea. as each Submission will be different. and as its encrypted oin submitting it should help the hacking

If it's being submitted by form to server 2, can't you just check the HTTP referer to make sure the request originated from server 1?

If you are using MSSQL why would you need to send data to your second server like that? If you store the shopping cart in the database both of your servers should be able to connect to the MSSQL server and get the shopping cart.

i know that MSSQL you can..

but the cart is going to be Access also. and some people might not want to use te MSSQL as it maybe slower than wanted so i'm making it so you can use MSSQL or use the access version side thats a form
