What are the uses of Response.Flush() method?
The Response.Flush() method is used to immediately send all content in the response buffer to the client, clearing the buffer to ensure timely delivery to the client.
The main purpose of the Response.Flush() method includes:
- Real-time output: During long-running operations, by using Response.Flush(), partial results can be sent to the client in real-time instead of waiting for the entire operation to complete before sending.
- Download file: Using Response.Flush() when downloading a file can ensure that the file content is promptly sent to the client without causing timeouts or interruptions during the download process.
- Streaming output: When producing a large amount of data or streaming content, using Response.Flush() allows for sending data to the client gradually, reducing wait time and memory consumption.
It is important to note that using the Response.Flush() method may increase network transmission overhead, so it is necessary to consider this when using it to avoid performance issues caused by frequent calls.
