But this theory=20 was wrong because an extra url with cookies does not fix=20 the problem like it does with a database. > Could you please tell us what server you're using?

Too bad though, since I=20 want to use encrypted cookies for security reasons. =20 PROBABLE CONCLUSION: Although Base64 is an encoding method (not an encryption=20 method) it is the ONLY method that actually works when=20 trying to obfuscate cookie values. Base64 is certainly not secure like an encrypted value might=20 be, but it is better than nothing I guess. I tested all=20 methods using cookies with the following results: standard webdna encryption --> fails 1/4 of the time method=3DCyberCash --> cannot be decrypted method=3DAPOP --> cannot be decrypted method=3DBase64 --> 100% reliable in dozens of tests Sincerely, Ken Grome Associated Messages, from the most recent to the oldest:
