Limiting Input size

[Brooklyn Linux Solutions CEO]

Is there a way error out of an entry which might be too large in a
form or a get string with $r->content or $r->args


I want to prevent an attempt to overflow the memory by sending
an arguement with 10 billion bytes.

I can do it after.  But without doing a read(), I'm wondering if
these shortcuts provide security protection in this regargd, or
if there is a better solution?
