Hi Guys!
I'm having trouble configuring an Apache 2.0.55 (32-bit; linux;) to
serve pre-compressed (gzip 1.3.5) html files (for inline browser
rendering) using AddHandler type-map.
Using the type-map, Firefox (1.5) and Safari (2.0.3) are not
displaying the content inline, they both want to download the
'application/x-gzip' instead. Both browsers behave properly when
un-compressed files are dynamically compressed via mod_deflate
(verified with ethereal included bellow).
I've included Ethereal summaries of the http for each of the tests
bellow.. I'm confused at the inconsistancies, and could not find a
combination of setting that would yeild inline viewable content from
pre-compressed html files
First I used the first index.var, see bellow, and tried all four
combinations of "AddType application/x-gzip .gz .tgz", "AddEncoding
x-gzip .gz .tgz" (enabled and disabled) in the httpd.conf. All combos
yeilded the same result; the browser wishes to download the file
instead of inline displaying it. The second encolsed Ethereal dump is
the same (excpet for time, tag...) for all four of the above trials..
'Content-Type: application/x-gzip' and no Content-Encoding despite the
directive in the index.var
Now when I change the file extention from index.xml.gz to index.xml.1
(updating index.var too), apache sends the file as the 'Content-Type:
application/xml', and no 'Content-encoding: gzip' as the index.var
specified. The browsers don't like the 'gibberish' and fail to
render.
I then tried added 'AddEncoding x-gzip .gz .tgz' to httpd.conf, change
the .var to 'Content-Eocoding: x-gzip', and changed the filename back
to index.xml.gz. I observed 'Content-encoding: gzip' but now the
'Content-Type: application/x-gzip'.
Serving precompressed content appears to be possible, but remains out
of my grasp. 'http://artific.com/articles/2005/03/01/2.php'; The
manual also indicates it is workable
'http://httpd.apache.org/docs/2.0/mod/mod_mime.html#addencoding'
I'm not able to downgrade apache to 1.3.x so mod_gzip is not feasible.
I'm not able to upgrade to apache 2.2.x to use the mod_filter tweak
for mod_deflate as
'http://httpd.apache.org/docs/2.1/mod/mod_filter.html' and
'http://issues.apache.org/bugzilla/show_bug.cgi?id=31145' illustrate.
I _really_ would appreciate any help folks can offer here...
Thanks in advance,
Vizzini
