let's say it is a HEAD request for a local static file. the default_handler calls ap_set_content_length which creates a C-L header. but then the body could be run through some length changing filter, such as mod_deflate or mod_include, invalidating the default_handler's C-L.
Then that filter must remove or modify the C-L.
in that case we want to update the C-L to reflect what's currently in the brigade. so we need to behave differently when there is no body at all, like proxy, and when there is a temporary body which will be thrown away shortly.
That sounds like spaghetti code to me. Fix the bug in the filters, not the side-effects. +1 on this patch as a temporary fix if you add commentary with it, but I'd rather have a server that isn't so fragile in the long term. ....Roy
