I'm processing form input on a web site that uses Perl CGI scripts
running under IIS 5 on W2K. The performance is fine using IE and
Netscape 7, but with Netscape 4.76 it takes 30 seconds to download a
simple page. I'm not setting any strange headers, and if I copy the
page source into a text file and open the file with Netscape 4.76, it
opens instantly. What could be slowing this down? |

Hello Jazzbass,
Do you have an URL to view the form (and/or the text version)?
Thanks

Hello:
Are you generating a complex HTML page with a lot of tables, CSS and
so on? NS 4 rendering engine is not very fast and could delay a lot
showing some pages. As maniac requests, please, post an URL and we
could try to solve your problem.

The problem seems to be caused by a redirection request. For example,
a login page sends the user's password to a Perl script that contains
the following statements:
$query = new CGI;
...
print $query->redirect(-uri=>"http://myhost/temp.html")
if ($pass eq $pwd);
This outputs the following http response:
HTTP/1.0 302 Moved
Location: http://myhost/temp.html
I've tried the redirect with "-nph=>1" but Netscape 4 is still very
slow.
The page loads instantly if I point Netscape 4 directly at
http://myhost/temp.html or if the url is the target of a link (<a
href="http://myhost/temp.html">), so the redirection seems to be the
problem. How can I speed this up?
Thanks,
Mike

Hello Jazzbazz,
I hate to ask again, but do you have an example we can access to help
diagnose the problem?
For example, I'm currently using Netscape 4.76 to post this request,
and can monitor both CPU time and network traffic (to help determine
the sequence of events and which step is slow). Without an example, I
can only guess at the cause. I can also add to joseleon's comment that
Javascript can also slow down Netscape 4.76 significantly as well.

Unfortunately, I can't modify the public site, and my test system is
not publicly accessible. But I am open to guesses. :-)
After more tests, it seems that a hyperlink with an href pointing to
the Perl script works fine, but a form action referencing the same url
is slow. The following files duplicate the problem on my system:
hello.html:
<html>
<body>
<a href="http://myhost/cgi-bin/temp.plx"><h2>Very fast</h2></a>
<form method="POST" action="http://myhost/cgi-bin/temp.plx">
<input type="submit" value="Very slow">
</form>
</body>
</html>
cgi-bin/temp.plx:
use CGI;
print new CGI->redirect(-uri=>"http://myhost/temp.html", -nph=>1);
temp.html:
<html>
<body>
<h2>Loads quickly from the hyperlink, slowly from the submit
button</h2>
</body>
</html>

Hello there, Jazzbass.
Would you consider a Meta Refresh as an acceptable way to re-direct?
As far as I know, the majority of browsers are capable of using this
method and I can check compatibility with the World Wide Web
Consortium if you would like me to.
Regards,
errol-ga.

In my application, a Meta Refresh won't work because the redirection
requires a run-time decision in a Perl script:
if (valid user)
redirect to input form
else
redirect to login page
Thanks,
Mike
