Expireing pages
Posted: Mon Jul 26, 2004 3:07 pm
Not sure where this goes, but lets try from here:
I have random number generator (avatar I think its called)
it prints a number on a page, and you have to type in the textfield in order to submit the form.
This is my problem. I think that this system can be easily tricked by BACK button and inputing the value again (textfiled type is password, but the page is loaded with the same random number)
Is there any way to prevent this type of abuse (somehow for page to expire, or maybe IP filtering (just came on my mind))
Any ways any suggestions would come in handy.
Thanks Ahead !
