I'm having problems with a PDF file which has a size of 1.4MB which I'm trying
to view over a SSL connection.

When viewing the page with IE 5.5 I can't use the "Open file from its current
location" option but I'm forced to use the "Save this file to disk" instead.
When pressing OK it pops up with an error message like "not able to open this
intranet site".

When trying to view the same page in Netscape 4.7 it immediatly opens part of
the PDF as an object. The problem here is that it looks like it only gets a
part of the document before disconnecting.

When I do the same with Opera ... lo and behold ... it works. Forgot to mention
that when I shift-click in netscape it downloads the file without any problems.

Here's a small part of the ssl_engine_log which pops up when I try the IE
approach:

[03/Oct/2002 14:50:42 11648] [info]  Connection to child 4 established (server

shutdown (server apache.duh.com:443, client 192.168.10.10)

And from the same log when I try it through Netscape:

[03/Oct/2002 15:07:47 11733] [info]  Connection to child 3 established (server
apache.duh.com:443, client 192.168.10.10)

And finally, when I use Opera:

[07/Oct/2002 11:39:40 13859] [info]  Connection to child 5 established (server
apache.duh.com:443, client 192.168.10.10)

As mentioned Apache has been compiled with mod_ssl and we're using
OpenSSL lib 0.9.6g. Configure string looks like this:

./configure --with-apache=../httpd-1.3.26

for mod_ssl and Apache:

SSL_BASE=/opt/SMCossl
./configure --prefix=/local/apache-1.3.26 --enable-module=proxy --enable-module
=so --enable-module=ssl --enable-module=rewrite --enable-module=info


Here's a small portion of the httpd.config:

Anything else which is needed here ?


Now, I've tried to find solutions to this here problem for some time now.
I've RTFM, I've read the FAQ, I've read miscellaneous postings here and there
outlining possible solutions to this problem (I guess its not just related to
PDF files??) and I've tried to add a few settings here and there to the config
without any success.

When I'm using the HTTP instead of HTTPS I have no trouble at all getting the
document from any browser so my thoughts is that it is mod_ssl which is the
problem (or browsers).


Anyone ?
