Single use URL's?

[WaveJam]

Forgive thyself if this has been covered. Didn't see it though. Looking for a way to generate some sort of one time use url to activate an IO command. You know, a disposable url that can only be used once.

Why? Because I'd like to allow someone (actually multiple people) permission to run a command ONCE and only once.

Any ideas?

i got it...

have two pages. the first one checks for a cookie on the users computer. if it exists, it redirects to your home page. if it doesn't, then it goes to a page with the iobridge code.

you could also use the same idea, but instead of a cookie check,write the ip address to a file, and then check if it exists. the first would be easier to implement, but the second is more secure. your call.

Thanks zerogx...

But whats to stop someone from bookmarking the second page? Or even saving a copy of that HTML locally and reusing. Maybe I should have named this something other than single use "URL's". I think I'm looking for something similar to one time use, randomly changing widget embed tags. I know its a long shot. But I thought I'd ask.

Thanks.

maybe incorporate into one page... have it check for the unique identifier (cookie/database record). then have it enable the code... like have a hidden css element come up.


r to continue my idea, use php, with session variables in the url. database records the usage of the variable and the ip address. have the php code check the referrer/hosted location to prevent offsite usage. after the variable is used, it no longer is valid.

if i may ask, what are you trying to do?

if i may ask, what are you trying to do?

clarification: if i may ask, what are you trying to protect (the function)? itd be somewhat easier if i knew what the goal was.

A way to achieve this is by having a database application where you can store a unique random string....Then you generate and store the random string and append it as parameter on the url (ie www.yoursite.com?param=asge43gds3) then on load you check that the parameter has only being executed once...
