There are many application in which may want to pass "state"
information between pages. For instance (based on an app
someone's written here) I may want to select a database
from an initial form and be able to bring up a generic
page that allows you to search on that particular database.
How do I pass information to this "generic" page?
The only viable methods in a form (at least that I can
see) is to pass the information as a value to a form field
or pass the information via the *name* of a form field
(i.e., you're limited to the values passed in the query).
The latter method allows you to pass the information tranparently
to the user. This seems a bit awkward - is there another
method?
For the non-form case, my application can add variables
to the query subset of the path and I can pass this transparently
via the POST method. In the form case, the query subset is
under control of the form (e.g., I can't stick query terms into
the form action) as far as I can tell.
