The \ex{cgi-scripts} structure provides functionality useful for
|
||||
writing CGI scripts in Scheme.

CGI scripts receive their parameters in various ways, depending on
|
||||
how they were called (e.g. by ``GET'' method). This procedure
|
||||
translates the delivered form data into an alist of decoded strings,
|
||||
using the environment variables set by the server
|
||||
(\ex{REQUEST\_METHOD}, \ex{QUERY\_STRING} (``GET'' script),
|
||||
\ex{CONTENT\_LENGTH} (``POST'' script)). So a query string like
|
||||
\codex{button=on\&\ob{}reply=Oh,\ob{}\%20yes} becomes alist
|
||||
\codex{(("button" . "on") ("reply" . "Oh, yes"))} This only works for
|
||||
GET and POST methods.
