Sample code:
-------------------
import std.stdio;
import std.json;
void main(string[] args){

   string text = "{ \"url\":\"http://www.boost.org\" }";
   JSONValue json = parseJSON(text);

   writeln(toJSON(&json));
   // prints: { "url":"http\/\/www.boost.org\" }
   // The same happens when writing to a file.
}
--------------------

The double slash "//" in the url is replaced by "\/\/".
Is that a feature or a bug? If the former, what is the
reason for this behavior and how to avoid it?

It is intentional. I searched the web for other json 
implementations that do the same thing and came up with this link 
for why:

"Allowing \/ helps when embedding JSON in a <script> tag, which 
doesn't allow </ inside strings, like Seb points out."



There's no way to disable it in D's std.json, but you don't have 
to either - it is perfectly correct according to the standard.

Thanks Adam! On the other hand: json is fine to be edited by humans and
in this case simple double slashes would be better. Thus a second bool
value to discriminate both variants where preferable. No serious problem
anyway ...
