(SQL Server) 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.

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

// Important: See this note about string length limitations for strings returned by sp_OAMethod calls.

    -- To specify a proxy, we can create a Chilkat HTTP object, set the proxy related properties, 
    -- and then tell the PDF object to use the HTTP object for any communications needs.
    DECLARE @http int
    EXEC @hr = sp_OACreate 'Chilkat_9_5_0.Http', @http OUT

    -- The port at which your HTTP proxy is listening for HTTP requests.
