:::tip
|
|
When working with an infinite stream of incoming data, it is obligatory to specify the MaxSize parameter, because endless data retrieval can cause hang-ups
|
|
|
|
If the connection is closed, an error occurs, or EOF is detected, the read is terminated in either case
|
|
|
|
Parameters with Binary data type can also accept file paths on disk and URLs
