Procedure Test
    Boolean iSuccess
    Handle hoReq
    Handle hoHttp
    String sJsonText
    Variant vResp
    Handle hoResp
    String sTemp1
    Integer iTemp1

    Move False To iSuccess

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    End

    // The PUT request to be sent will look like this:

    // PUT /request HTTP/1.1
    // Content-Type: application/jsonrequest
    // Cookie: JSESSIONID=1234
    // Content-Encoding: identity
    // Host: json.penzance.org
    // Accept: application/jsonrequest
    // Accept-Encoding:
    // Content-Length: 72
    // 
    // {"user":"doctoravatar@penzance.com","forecast":7,"t":"vlIj","zip":94089}

    // First, remove default header fields that would be automatically
    // sent.  (These headers are harmless, and shouldn't need to 
    // be suppressed, but just in case...)
    Set ComAcceptCharset Of hoHttp To ""
    Set ComUserAgent Of hoHttp To ""
    Set ComAcceptLanguage Of hoHttp To ""

    // Suppress the Accept-Encoding header by disallowing 
    // a gzip response:
    Set ComAllowGzip Of hoHttp To False

    // If a Cookie needs to be added...
    Send ComSetRequestHeader To hoHttp "Cookie" "JSESSIONID=1234"

    // Add the Content-Encoding: identity header.
    Send ComSetRequestHeader To hoHttp "Content-Encoding" "identity"

    // Modify the default "Accept" header:
    Set ComAccept Of hoHttp To "application/jsonrequest"

    Move '{"user":"doctoravatar@penzance.com","forecast":7,"t":"vlIj","zip":94089}' To sJsonText

    // IMPORTANT: Make sure to change the URL, JSON text,
    // and other data items to your own values.  The URL used
    // in this example will not actually work.
