So is "rewrite_by_lua" also evil?

Strange, looking at the message from Maxim to Igor, that this hadn't
been changed before.
If you refer to the message I sent just before yours, you will find I
am still seeing this behaviour for some requests and that I rolled
everything back to my last known working config.

Perhaps the work around need to go into some other one of the modules I use.

I'll look into applying the patch to the 1.0.8 core directly and retry later.

Nice.

I will be building openresty rpms for redhat presently. Wanted to try
some of the elements first.
