Subject: [PATCH] Begin work on redirector webapp. The logic for redirecting
 wiki pages -seems- consistent with how the archives are generated but...
 nginx is normalizing the %2Fs into slashes and therefore not able to access
 any files with that escape sequence (e.g. Gold%2FSilver). Might need to find
 another character to escape / with.

+ might work, it's semantically acceptable (e.g. "Gold+Silver" in place of "Gold/Silver") although this character is sometimes interpreted equivalently to a space. Regardless, nginx seems to be happy with it so might go with it.

May also need to test on a web host e.g. my old tripod account to see if assumptions hold up there too.
