Why implement in httpd? Why not use existing solutions e.g. nscd works well. It would have to be investigated whether something like nscd would give enough of a performance enhancement, or in environments where this is not possible (win32?) whether a cache would improve things. This is why this bug is marked as "enhancement" :) Windows Server has its own DNS implementation, and recursive DNS servers such as Unbound are available cross-platform, so the Windows case is covered. Of course there's no httpd code to benchmark against, but external cacheing resolvers offer good performance without adding complexity. |
