Hi,

I have a table users wich the users can edit and save if they are login.  
Now if this user is making an transaction(air-flight) they go to a  
different url (partner). What is the best application-theory the submit  
the users-values such as name, surname ect into the partners-formfields?

example  
1)website a: \> login  
2)website a: \> select flight \> submit  
3)website b: \> select airliner + times  
4)website b: \> fill in the required form-data (name, surname,adress ect)

If they are in step 4, the form-data is filled in by the database of  
website a…

Is this possibly…or better what is the solution the exchange data  
between 2 applications.

Grtz…remco
