easy:SetOpt_MaxAge_Conn(age)
The "connection cache" that holds previously used connections. When a new
request is to be done, it will consider any connection that matches for
reuse. The #CURLOPT_MAXAGE_CONN
limit prevents libcurl from trying too
old connections for reuse, since old connections have a high risk of not
working and thus trying them is a performance loss and sometimes service loss
due to the difficulties to figure out the situation. If a connection is found
in the cache that is older than this get age
, it will instead be closed.
