Some forms on web-pages need to be filled by an URL,
some URLs contain URL of another page in parameters (after "?").
A script I wrote in order to demonstrate a bug in versions
of www4mail software higher than 2.2 causing two slashes to
be erroneously substituted by one slash:
#!/usr/bin/perl
$_ = $ENV{'QUERY_STRING'};
print "Content-type: text/plain\n\nParameters: $_\n";
if ( $_ eq 't=http://abc' ) {
print "two slashes\n";
}
elsif ( $_ eq 't=http:/abc' ) {
print "one slash\n";
}
else {
print "something else\n";
}
A letter to five www4mail servers (kabissa doesn't reply to me):
source http://www.lena-kiev.f2s.com/test2.pl?t=http://abc
Results:
www4mail version 2.2 (www4mail@unganisha.idrc.ca, www4mail@web.bellanet.org):

In last case, besides unnecessary encoding, two slashes also are
erroneousy substituted by one slash. In all three cases URL on
statistics page contains one slash.
