Detailed Description
BIO node to handle socket IO for squid client side If bumping is enabled this Bio detects and analyses client hello message to retrieve the SSL features supported by the client

Member Function Documentation
◆ Create()

staticinherited |
Creates a low-level BIO table, creates a high-level Ssl::Bio object for a given socket, and then links the two together via BIO_C_SET_FD.

◆ flush()
|
inlinevirtualinherited |
Flushes any buffered data to socket. The Ssl::Bio does not buffer any data, so this method has nothing to do

◆ read()
The ClientBio version of the Ssl::Bio::read method If the holdRead flag is true then it does not write any data to socket and sets the "read retry" flag of the BIO to true

◆ setReadBufData()
|

Sets the buffered input data (Bio::rbuf). Used to pass payload data (normally client HELLO data) retrieved by the caller.
