Removing ETag from header

[ProxRocks]

interesting...

i seem to recall a conversation with sidki back in the day when we e-mailed every so often, that "theoretical" entities really aren't intended to be included in his config, "out in the wild" entities are well-documented by sidki...

so i can assume his config didn't worry about ETag tracking because it was not encountered "out in the wild"...

probably safe to assume that Scott's "default" config didn't include it for the same reason...


just speculating, who knows...
at any rate, i'm glad it was pointed out and we are all protected from this now
