public HttpWebRequest Encode(
RequestFields fields,
string path,
byte[] postedData
)
fields
The Leadtools.Jpip.RequestFields to be transmitted to the JPIP server.
path
A System.String value identifying the server URI.
postedData
An array of bytes to be sent in the request message body. This value can be null.
An System.Net.HttpWebRequest ready to transmit the JPIP request to the server.
If postedData is specified, the System.Net.HttpWebRequest will be created with a POST method and all fields will be encoded to the message body.
You can use the postedData parameter to optimize the process of encoding when sending cache information.
If postedData is null the System.Net.HttpWebRequest will be created with a Get method with the fields encoded in the request URL.
