Note:
The Post function only runs if a form is certified. Acrobat and Adobe Reader cannot verify that the form is certified until after the initialize event initiates. To use the Post function on certified forms prior to the form rendering, use the docReady event.
Post(s1, s2 [, s3 [, s4 [, s5 ]]])

s4 (Optional)

If you do not include a value for s4, the function sets the code page to the default value. The application ensures that encoding of the data to post matches the specified code page.
s5 (Optional)
A string containing any additional HTTP headers to be included with the posting of the data.
If you do not include a value for s5, the function does not include an additional HTTP header in the post.
