>Description:
Older versions of Apache send "Last-modified:" instead of "Last-Modified:". 
The proxy module does not recognize these (slightly wrong) headers.

In the function ap_proxy_cache_update
the response headers are searched for "Last-Modified" 
using ap_proxy_get_header.

No last modified date is found and the actual date is used.

The same is true for "Content-type:" and "Content-length:"

Maybe mod_proxy should be more tolerant to the behaviour of it's ancestors :-)
>How-To-Repeat:

make the search in ap_proxy_get_header case insensitiv
