Likely from invalid headers being sent from client, but regardless there should
not be an exeception thrown when trying to read the Request headers.

Reproducible: Sometimes

Steps to Reproduce:
1. Request comes into webservice (with corrupted headers?)
2. Try to enumerate/read the header values
3.
Actual Results:  
Exception is thrown

Expected Results:  
header collection populates and can be used

Parameter name: length
