Port a lighttpd module from version 1.4.50 to 1.4.57

We have a few old, but still useful, modules that works fine in lighttpd 1.4.50. It doesn't work in 1.4.57 because there's been a number of changes in the internal structures. As far as we can tell the changes are not huge and affect just a couple of files. Your job is to port our changes and of course test them really well (we don't want to be beta testers of your work or have a lot of back and forth) - your deliverables must work. We would give you access to a private repo which is a copy of the public one with our changes, which are not public because they're too specific for us. For reference, the file with the merge conflicts is this one: [login to view URL] (there's a few others but those are trivial to fix) It _seems_ like one day of work for a experienced C programmer; bid accordingly. Note: No placeholder bids please.
