Re: How to make mod_svn_dav return a last-modified header?

I'm confused about this rpm's name, by the way. The caching headers
were in revision 6636. Subversion 0.26 was based on revision 6550 or
so. What does the "-6662" mean -- where did the rpm come from?

I tried to detect the caching headers with ethereal, in a lynx dump
and then in a checkout, no luck. So something is wrong here. Dang
it, I *know* Ben and did an ethereal dump after we made the change,
and we saw the expected headers in there, so what happened? :-) I
don't know yet...

   $ lynx -head -dump http://localhost/repositories/basic_tests-1/iota
   HTTP/1.1 200 OK
   Date: Thu, 07 Aug 2003 22:01:50 GMT

During which ethereal said:

Hmmm, no caching headers. Then I tried a checkout:

   $ svn co http://localhost/repositories/basic_tests-1
   A basic_tests-1/A
   A basic_tests-1/A/mu
   A basic_tests-1/A/B
   A basic_tests-1/A/B/lambda

   A basic_tests-1/A/B/E/alpha
   A basic_tests-1/A/B/E/beta
   A basic_tests-1/A/B/F
   A basic_tests-1/A/C
   A basic_tests-1/A/D
   A basic_tests-1/A/D/gamma
   A basic_tests-1/A/D/G
   A basic_tests-1/A/D/G/pi
   A basic_tests-1/A/D/G/rho
   A basic_tests-1/A/D/G/tau
   A basic_tests-1/A/D/H
   A basic_tests-1/A/D/H/chi
   A basic_tests-1/A/D/H/omega
   A basic_tests-1/A/D/H/psi
   A basic_tests-1/iota
   Checked out revision 1.
   $

And ethereal saw nothing about caching or Last-Modified during the
checkout:
