Hi,

the doc says: large\_client\_header\_buffers number size

What’s the meaning of number? At most number of large headers can be  
‘processed’ at once? Per request or globally? If yes, what happens to  
the request that exceeds that limit?

I believe the description is quite complete and answers all of  
your questions.
