Using POST to preserve state

[Mark]

I'm aware of how to preserve state using session, application variables,
view state, query strings, etc. I'm told that you can use POST to do a
similar state preservation. How does this work and/or could someone post a
quick example of how to store and retrieve? Thanks in advance.

Browsers can either GET or POST data back to the server.

GETs pass data on the query string.
POSTs pass data in the form.

Anytime you have a field in a form that uses the POST method, you are
preserving state using a POST. ViewState stores its data in a hidden field
and is an example of a POST.

Thanks. Is there a way to use the POST without including existing form
fields?

Thanks again.

Don't think so. A POST posts back the form and will include all fields on
it.
