Public bug reported:
Binary package hint: ruby1.8
Using firefox to access a CGI that implements conditional-GET, using the
very same ruby script on all three machines, I access the page to obtain
the LAST-MODIFIED and ETAG; firefox will then automatically provide
these as IF-MODIFIED-SINCE and IF-NONE-MATCH respectively.
the following two lines are put into the cgi program (no mod-ruby, just
cgi)
<li>IF-MODIFIED-SINCE: #{ENV['HTTP_IF_MODIFIED_SINCE'] || 'n/a'}
<li>IF-NONE-MATCH: #{ENV['HTTP_IF_NONE_MATCH'] || 'n/a'}
when run in Debian 4 or Debian 5 with
Debian 4: ruby 1.8.6 (2008-03-03 patchlevel 114) [i486-linux]
Debian 5: ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]
the above prints:
# IF-MODIFIED-SINCE: Tue Apr 14 10:08:50 -0400 2009
# IF-NONE-MATCH: 1239718130
but when run in Ubuntu Server 8.10 with
ruby 1.8.6 (2007-09-24 patchlevel 111) [i486-linux]IF
(which is pretty ancient, no?)
# IF-MODIFIED-SINCE: Thu, 01 Jan 1970 00:00:00 GMT
# IF-NONE-MATCH: 1239719740
ie, the IF-NONE-MATCH is reported correctly, but the IF-MODIFIED-SINCE header
is being read as zero.
firefox reports that page as "Modified: Tue 14 Apr 2009 10:50:27 AM EDT"
suggesting the Last-Modified header returned by the previous CGI call is
correct, and since the same browser works with the other Ruby versions, firefox
is very likely returning that value correctly as If-Modified-Since, it just
isn't showing up in the HTTP_IF_MODIFIED_SINCE key's value.
** Affects: ruby1.8 (Ubuntu)
