Revision: 4438 Author: hans URL: http://bknr.net/trac/changeset/4438 Patch by Peter Seibel, his words: I think the actual problem I had was some code that did essentially: (with-foo-output ((send-headers)) (expand-template-file)) where expand-template-file calls code that uses post-parameters to get at, well, post parameters. It's not clear how to easily turn that code inside out so all the parameters are gathered in advance of calling send-headers.
