SunOS 5.7, newest gcc
>Description:
We are doing some proxying/load-balancing to several upstream servers which have different "ServerName"s.
When mod_dir issues a trailing slash redirect on a URI which corresponds to the name of a directory, it uses that "ServerName" in the "Location" http-header field. But the client does not know anything about our exotic DNS.
>How-To-Repeat:

>Fix:
I suggest to modify the source of mod_dir according to the following output of "diff". What do you think? Is there a problem with a certain class of clients which do not find a redirection URL without protocol and hostname?

$ diff mod_dir.c_original mod_dir.c
136,137c136,137
<         ap_table_setn(r->headers_out, "Location",
<                   ap_construct_url(r->pool, ifile, r));
