It seems like there is a setting in the Apache server to change so
that the server along with the actual file data also sends "something"
that triggers the expansion. What this could be I don't know, and
therefore I am asking here.
If I understand correctly, the files are already
compressed on the original server (the file on
disk is abc.xml.gz, as opposed to abc.xml), right ?
Then it probably has something to do with the
HTTP headers sent in the response. Apache sends
the response to the browser, with a HTTP header like
Content-type: application/gzip
or something similar, so that the browser
believes that the .gz file is the original
content, and proposes to the user to download it as such and save it to disk.
Instead, what you want is that the browser would
"believe" that the gzipped file is only a way to
transport the original content more efficiently,
and that the real content is the xml file, unzipped.
So you want the response to be sent with HTTP headers like
Content-type: text/xml
Content-transport-encoding: gzipped
so that the browser would unpack the zipped file and present the XML document.
I am not quite sure of the exactness of the
header names or form above, but it's the
idea. I am unfortunately also not quite sure
how to configure Apache to set the headers that
way. It probably requires some module
in-between. I'm sure a neat little mod_perl
module would do fine here, but that may not be
what you're looking for, and there might be a
simpler way using Apache directives only.

Perhaps the AddEncoding directive would help? I
don't really know as I have not tried it, but it is worth a try.
http://httpd.apache.org/docs/2.2/mod/mod_mime.html#addencoding
Combined with the AddType directive to tell the
system that it is an xml file, it may well do what is needed.
http://httpd.apache.org/docs/2.2/mod/mod_mime.html#addtype
So something like this (I think):
AddEncoding x-gzip .gz
AddType application/xml .xml.gz
Or maybe the type needs to be text/xml, both are
valid MIME types for xml documents but I don't
know which is appropriate to what circumstance.
