vibr ed1e4428c5 *move general procedures ESCAPE, UNESCAPE and their helper procs from 
url.scm to uri.scm
-->Parser/Unparser for HTTP 1.1 URIs is now complete and resides in
url.scm; Encoder/Decoder applicable to URIs in general resides in uri.scm.
(All has been rewritten from scratch, next to nothing of Olin's code
is left).

vibr 44100cbf5e Added type NO-BODY for responses which must not contain a message-body

GET-HEADER in utilities.scm and wasn't exported anyway

vibr ffbe3b21cd factor out parsing of content-length header value -> GET-CONTENT-LENGTH 
generalize parsing of content-length header value to parse all header field
values of the form 1*DIGIT -> GET-NUMERIC-FIELD-VALUE

add XML namespace declaration to html element
 2004-08-13 15:49:19 +00:00
vibr 6969b80206 - move XHTML stuff from responses.scm to htmlout.scm 
- new function EMIT-PROLOG

- adapt macro %hack-attr-elt: special treatment of xmlnsdecl-attr
(this is not nice, but the only alternative was hard-coding the XML
namespace declaration into the various handlers)

vibr 96f0ae41d5 -move XHTML stuff from responses.scm to htmlout.scm 
-don't use WRITE-STRING with \n (\n within strings is not in R5RS),

vibr 1bdac52ad6 adapt calls of make-error-response: remove tautologous description of errors 2004-07-30 22:26:50 +00:00
vibr 7c7be57a22 changes to make-error-response: 
(1)no special treatment of first "optional" argument
- rationale: a different number of args is required depending on the
specific error code

(2)use close-html to write out all _effectively_ optional args

(3)generated html-pages are valid XHTML 1.0 Strict

(4)require header Allow for 405 errors

(5)more exact descriptions of errors in generated html-pages
