The page is served via regular HTTP and not SSL.
>Description:
Take this simple CGI script:
----
#!/usr/bin/perl
print "Content-type: text/html\n\n";
open (F, "/full/path/to/some/page.html");
while(<F>) {
print $_;
}
close (F);
----
It worked on Apache 1.2.5, and functions correctly when run from a unix shell.
After upgrading to Apache 1.3.1 and then 1.3.2, only the first 4071 bytes of the
file are included in the HTTP output - or exactly 4096 bytes including the
"Content-type: text/html\n\n" header.
Any idea what's going on here?
Thanks,
Jack
>How-To-Repeat:
Using the script above and a suitable long HTML file.
