[Techtalk] configuring Apache2 for pdf

[Helen]

I recently have been receiving complaints from people accessing my web 
site that they cannot see pdf files in line with their browser.  They 
have to "save target as" and then open the file.  I've been searching 
the apache web site, for a configuration file example or reference to 
handle this, with no luck.

    Any suggestions?  I am using SuSE9.0 with  the default apache2 
server.  Everything else seems to work.  I just had to rebuild my server 
again from a hard drive crash and I had the same problem previously.
