How are you going to test byte length before adding it to the cookie? Come on, every way you cut it a cookie solutions is a bad idea. One character too many and the cookie is corrupted.

No you can't put a complex var in a cookie (it's just a text file - you can only write a string to a text file) and yes, WDDX is just a string. Due to it's verbosity, if you're running CFMX I definitely recommend creating an XML packet and storing that in the cookie - not a WDDX packet. You're going to find that WDDX packets will become real big real fast.... and then you can't stuff them into cookies.

Follow these steps: 1) form is posted 2) create a new query using QueryNew() 3) add a row to the query using QueryAddRow() 4) add all the form data to the row in the query usingh QuerySetCell() 5) serialize the query into a WDDX packet using CFWDDX 6) set a cookie with the value of the WDDX packet using CFCOOKIE Then wherever you need the data..... 1) deserialze the WDDX packet in the cookie 2) voila you have a query with all form data in it 3) do whatever ya need to to re-create your form as it was left HTH Bryan Stevenson B.Comm.
