Hi,
I've writen a documentation, using the Scribble tool. When I want to display
functions, I use the @schemeblock[ ] tag.
But if there is some comments like "i love foo", there are not displayed.
Could you explain me a way for display the comments, it's better for explain
functions when people r

Hi all,
I've misunderstood the bindings from the webserver.
I have a cgi program wich displays a webpage with an input field named
number at 127.0.0.1/cgi-bin/input and wich calls (via a form)
/cgi-bin/extract-input.
For example, after sending, the url could be
127.0.0.1/cgi-bin/extract-input?num
Hey,
with the command line mzscheme it works, so i don't know where is the
problem :
actually, try.cgi is this one :
#!c:/Racket/mzscheme.exe
(display "HTTP/1.1 200 OK \r\n")
(display "Content-type: text/plain; charset=iso-8859-1 \n\n")
(display "hello")
The apache access log says :
127.0.0.1 - -
Hi all, i've just understood the CGI way-of-life (yes, i'm happy)
First, i have a perl super-easy script (file saved as test.cgi) who prints
"hello", this is it

print "Content-type: text/plain; charset=iso-8859-1\n\n";
print "hello";
It works perfectly,, when i'm
Hi all,
i have a problem within the creation of "dynamic links" :
I have a racket blog, and i have a function who takes all posts from a
database (posts = body + title ) and creates a link (make-url ... request)
with the title who refers to a new page that display the body. This
perfectly works.
nobody has an apache configuration to run Dr.racket files in localhost ? =/

Hi,
i have a local apache server (win$) and i would like to know how can i
configure it for that, when i'm connecting at 127.0.0.1, it launches a

actually, index.rkt is a simply webpage

Hi,
i learn with-handlers mechanism, and i don't understand what's wrong in this
piece of code ?
#lang racket
(require xml)
(define a-good-string "hi there!")

(define (panoramix s)
(with-handlers ((exn:invalid-xexpr? (lambda (e) 'UFO)))
(string->xexpr s)))
Hi,
i think that the problem is the \ character, because this works :
#lang racket
(equal? (regexp-replace* "" (path->string (build-path "C:\\")) "/")
(regexp-replace* "" (path->string (build-path "C:\\")) "/"))
and returns true

Hey noel, thank you, it works perfectly.
However, i have the following problem : i can't modify my cookie-value ...
my blog starts with

Hi all,
i'm reading the documentation on cookies (net/cookie), and i try to save

For example, the cookie "my-cookie" has this content :

How can i just extract the string "bla bla" or blabla ?

Hi,
As you know in other languages, it exists failures with security of
