[Webware-discuss] Advice : Form State Storage

[Ian S. <Ian...@et...>]

I have a form that gets posted back to the same URL time and time again =
as the user refines a list of records on that form by adding "filters".

Filters boil down to additions to a SQL WHERE clause.

The options for saving these filters between posts appear to be :

* Client Cookie.
* Form fields for each filter
* Session store keyed from hidden form field
* VIEWSTATE hidden form which contains pickled, Base64d and "signed" =
filters.

Of the options I prefer the session idea because it avoids sending more =
data down to the client but how will I clear these up and when? A user =
session could get large fast...unless I pickle to a file/database and =
put the id of that file/record in the hidden field?

I searched the newsgroup but I never found a real definitive answer. Is =
there one?
