Log Message:
Fix for bug #1388 - handling of invalid If-Modified-Since date values. 
Some proxies appear to send invalid date strings (in this case, multiple
valid date strings stuck together with commas). While the spec says that 
we _should_ raise Bad Request, Apache appears able to handle these values 
due to a happy coincidence in the way they parse date strings. Rather 
than be draconian about the spec, I've changed IMS handling so that invalid 
date strings are simply ignored as if the header weren't there at all. This 
is closer to the behavior people would expect based on other servers.
