This demonstration on how to apply HTTP Silent Post with your Dynamic Registration.
First:
Create your Dynamic Registration form with the necessary fields(FirstN,LastN,UserN,Pass,ConfirmPass,Display,Email).
NOTE: the shortname tokens of your fields, because you will be referencing these names. You can add more fields and map them to your DNN Core fields if you like but the above fields are necessary.
Second:
Let's say for example your DR page URL is:
http://www.website.com/SilentRegister.aspx
You can silent register to it by using the following URL from anywhere on the web:
http://www.website.com/SilentRegister.aspx?SPOST=true&FirstN=Silent&LastN=Post&UserN=SilentPost&Pass=password&ConfirmPass=password&Display=Silent Post&Email=silentpost@google.com
NOTE: you need to replace the information you want passed though. It resembles querystring variables. The example above will generate a new user:
First Name: Silent
Last Name: Post
Username: SilentPost
Password: ********
Confirm Password: ********
Display Name: Silent Post
Email Address: silentpost@gmail.com
Your DR page would show: ***User Just Added Via Silent Post***
This concludes the small informative demonstration on how to use HTTP Silent Post.
