yes.  It works ok with a normal form, I'm only able to
see the fault when I use multipart/form-data encoding.

Here's my test page :

#!/usr/bin/perl

use CGI;

my $q = new CGI;

#print $q->header('text/html');
print "Content-type: text/html\n\n";

my $hidden = "hidden";
my $text = "text";
my $checkbox;

if ($q->param('hidden')) {
     $hidden = $q->param('hidden');
     $text   = $q->param('text');
     $checkbox = $q->param('checkbox');
}

print qq {

<FORM METHOD=POST ENCTYPE="multipart/form-data" action="testform.pl">

<INPUT TYPE="text" NAME="text" VALUE="$text">
<INPUT TYPE="hidden" NAME="hidden" VALUE="$hidden">
<INPUT TYPE="checkbox" NAME="checkbox" VALUE="checkbox">

<INPUT TYPE="submit" VALUE="run">

</FORM>

};

my @names = $q->param;
foreach my $name (@names) {
     my $param = $q->param($name);
     print "$name : $param<BR>\n";
}



And if I feed it smartquotes stuff from winword via IE 5.5, it does
exactly as you describe for apache 2, but is ok for apache 1.3.

So in some way, apache 1.3 must be dealing with it, but 2.0(.48)
is broken, or at least, not having whatever it takes to deal with the
IE breakage.

I can't sniff the traffic all that well, as I don't really know how
to do it, but is this something that should/could go into an apache 2
bug report?  I don't think we'd be the only site that's running into
this problem, we're just pretty keen to get all our (complex!)
stuff onto apache2 :)

It has been awhile...

I have not tested in 1.3, but if I find time I might try to investigate if
it does indeed manage to recover from the corruption.

That is not very hard, use Ethereal: http://www.ethereal.com/

As it is not a bug with Apache, you should not file it as a 'bug' bug
report. But, if it can be determined that Apache 1.3 is proof that this
corruption can be corrected, it might be worth considering filing an
'enhancement' bug report. We'll need to investigate more first.
