Normally when creating a non-symbolic shared library, undefined

These options disallows such undefined symbols.

Did your browser send digest credentials on the ajax request? You can

Not by default, see the MaxMemFree directive. The conventional wisdom
is that some other req on that thread will also soon need the same
