Forum OpenACS Q&A: Form Data in application/x-www-form-urlencoded Format

With one website, in particular the forums package, I am trying to specify what charset I am using with reference to http://dqd.com/~mayoff/encoding-doc.html#multipart-data.

I have added ns_formfieldcharset _charset and set form [ns_conn form] before form get_values message and this allows me to use form or message..

The problem is the form itself needs to be created with -method get for the encoding to work. Obviously this result in "Request-URI Too Large" with long posts. Am I missing something here for it to work with post method too?

Thanks in advance,
