I found this bug while investigating bug# 75637.
BUILDS:
2001-04-25-04
STEPS TO REPRODUCE:
1] Please visit URL above.
2] Select any option from select.
3] Click "Submit"
EXPECTED RESULTS:
Form should be submitted & reponse from CGI should arrive quickly.
Text Box Value is: TextValue
Select Value is: SelectValue2 [ASSUMING YOU SELECT OPTION2]
ACTUAL RESULTS:
It takes more than 30 seconds to submit form & to get response from CGI.
ACTUAL FAILURE:
The CGI used for this is like following.
********************************************************************************
#!/usr/local/bin/perl
require "cgi-lib.pl";
print "HTTP/1.1 200 OK";
print "Content-type: text/html\n\n";
MAIN:
{
&ReadParse(*input);
$resultsdir = "results";
$textval = $input{'temptext'};
$selval = $input{'tempsel'};
print "<HTML>\n";
print "<HEAD>\n";
print "<TITLE>CGI Test</TITLE>\n";
print "</HEAD>\n";
print "<BODY>\n";
print "<H2>Text Box Value is: $textval</H2><br>\n";
print "<H2>Select Value is: $selval</H2><br>\n";
print "</BODY>\n";
print "</HTML>\n";
}
exit(0);
********************************************************************************
if we do NOT use line [print "HTTP/1.1 200 OK";] in above CGI then it works
fine, [but in that case bug# 75637 shows up]
This bug occurs if we use line [print "HTTP/1.1 200 OK";] or if we completely
take out both lines [print "HTTP/1.1 200 OK"; print "Content-type:
text/html\n\n";] from code.
RESPONSE TIME IS HUGE.
Darin,
This happens when even when we do not have the following two lines in the
script.
print "HTTP/1.1 200 OK";
print "Content-type: text/html\n\n";
Turning off Keep Alive, causes the page to load fast and we do not see the
problem.
********************************************************************************
#!/usr/local/bin/perl
require "cgi-lib.pl";
MAIN:
{
&ReadParse(*input);
$resultsdir = "results";
$textval = $input{'temptext'};
$selval = $input{'tempsel'};
print "<HTML>\n";
print "<HEAD>\n";
print "<TITLE>CGI Test</TITLE>\n";
print "</HEAD>\n";
print "<BODY>\n";
print "<H2>Text Box Value is: $textval</H2><br>\n";
print "<H2>Select Value is: $selval</H2><br>\n";
print "</BODY>\n";
print "</HTML>\n";
}
exit(0);

from mtg w/gagan: move target milestone to 0.9.2. If after investigation, will
move back to 0.9.1 time permitting.

I don't think the HTTP header line at the top matters since the apache server
would strip it out and add its own (and so you shouldn't even be adding that)
but what is interesting is that layout doesn't start drawing anything till the
network (keep-alive) times out.

http/1.1 servers are not required to send a content-length header.
there are three ways of detecting EOF:
1- content-length header
2- chunked transfer encoding
3- server closes the socket connection

This bug is invalid. It is a server/cgi problem.
Attached is the results of proxying via ssltap. Note that the server responded
with a keep-alive header but without either sending a content-length or chunking it.
Not much that the client can do in that case.
U should use iWS60 or iWS41 to get HTTP complicance wrt keep-alives and chunking.
I'am using the same test case as mentioned in the above URL but proxying using
ssltap via vault:2000.
