.SH SYNOPSIS
|
|
|
|
|

|

This option determines whether libcurl verifies the status of the server cert
|
|
|
|
|
using the "Certificate Status Request" TLS extension (aka. OCSP stapling).
|
|
|
|
|
|
|
|
|
|
Note that if this option is enabled but the server does not support the TLS
|
|
|
|
|
extension, the verification will fail.
