Multiple Sequential Escape Characters in a URL

I have a URL on R5 that works just fine. We are converting to R6 and can you beleve it, it doesn’t work. The document key in the URL contains a date (complete with the “/”'s). We convert each “/” in the date to “%2f”. I have references about multiple sequencial escape characters having problems, so we modified the NOTES.INI parameter HTTPAllowDecodedUrlPercent=1 with no luck. I have removed the “/” completely from the document key and the key field on the view. This works. This lookup is used in multiple applications thru out our system. Is my only option to go modify each occurance of this lookup? Thank You in advance for any help.
