If this is not what you meant by adding this line then what does it do, I don't use khttp or for that matter know what that is.

Your initial complaint was that you couldn't use Jemplode to auto-update Hijack when it was in forced-DC mode.

That's because hijack doesn't enable KFTPD in DC mode, and Jemplode can only update Hijack through KFTPD.

So, by telling Hijack to enable "DC_Servers", you solve the problem, and now Jemplode can update Hijack even if it's in DC mode.
