Summary: Content-disposition filename is not working correctly
Product: Apache httpd-2
Version: 2.0.58
Platform: Other
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Core
AssignedTo: bugs@httpd.apache.org
ReportedBy: rbaily@servicebench.com
CC: rbaily@servicebench.com
It appears that somewhere between 2.0.48 and 2.0.58 the setting of the Content-
Disposition to set the file name for content returned broke. We are using
Tomcat 5.0.28 and modJK 1.2.15. I have put the example servlet code below.
When you run the URL the browser pops up with the file name "TestServlet.doc"
instead of "test_file_name.doc". I don't believe this to be a Tomcat issue
since it works with HTTP 2.0.48 and not with HTTP 2.0.58.
I ran http://dev.servicebench.com/rbaily/servlet/TestServlet on my system with
this test servlet.
Please let me know if there is anything I can do to clarify or help. Thanks!

A similar application does work in my environment. Please provide the following
information:
- Browser you use. Especially please try with both IE and Firefox.
- Please capture the HTTP conversation either with a tool like livehttpheaders
for Firefox or provide a network sniff of the request and the response.

Forgot one thing: Please provide a network sniff with 2.0.48 and one with a
later version >= 2.0.49 where it does not work as expected.

It appears that this was introduced in 2.0.49. This morning I built and
installed 2.0.49 and had the same issue while using 2.0.48 does not. I looked
at the change list and didn't see anything obvious that looked related.

Ok, thanks for the push in this direction. I've done more research and seem
to be at the root of the problem which looks like it was a combination of
configuration mistake on my part and IE behavior. I apologize now if I've
wasted anyone's time.
Here are snapshots using tcpdump for 2.0.48 and 2.0.58.

I have the mod_deflate module active. So what happened is that our
configuration had the regex in there for IE (BrowserMatch \bMSIE !no-gzip !
gzip-only-text/html) which according to some other text did not work due to a
bug in mod_setenvif up to 2.0.48. So as you can see from the captures the
content was not being compressed in 2.0.48 but was in any version after due to
the mod_setenvif fix. I did find that this does work for Firefox even with
the compression. So it appears that there is an ongoing issue with the way
that IE handles the content-disposition when the result is compressed.
So I don't know if there is a good way to document this for future reference
for other. I'll see if I can do anything to start the Micorsoft machine in
motion if that is even possible. Again, sorry if this wasted anyone's time.

I looked through 2.0.48->2.0.49 changes and am stumped.
I suggest you discuss with the Tomcat folks which web server behavior inflences
the generation of that header field.

Thanks for feedback. So I mark the report as invalid. I currently have no good
idea where to place this information, but it would be very kind of you if you
could add any further information regarding this problem just to this report. So
once we have found a good place to store this information we can take it from
here and it does not get lost. Furthermore other users can search bugzilla by
its own search capabilities or via a search engine such they possibly get this
information.
