(Android™) PDF LTV through HTTP Proxy or SOCKS proxy

See more PDF Signatures Examples

When signing with long-term validation and/or timestamping from a TSA server, the Chilkat PDF object will communicate via HTTP (and HTTPS) with the certificate's OCSP URL and with the timestamp server. This example shows how to specify an HTTP or SOCKS proxy if your environment requires the connection to go through a proxy.

Note: This example requires Chilkat v9.5.0.85 or greater.
