So, can I post variables to another page without user interaction?
Say, I have 3 different pages linked off the primary page, and each link
needs the same or different information for different purposes.
Can I programmatically tell it which vars to pass, without having someone
click on something other than the <a href>?
*starting to understand*
...i think.
