Doubt in 'response committed' in 'jsp:forward' - HFSJ pg 412

[Arvind Sampath]

When will the response actually get committed? As far as I know, the response will be flushed if the flush() method is invoked explicitly or the response in the buffer is more than the buffer size. Am I right and/or is there something that i left?

HFSJ pg:412 says in reference to <jsp:forward>

When a forward happens, the resource to which the request is forwarded starts with a clear response buffer! In other words, anything written to the response buffer is thrown out.

Is this behaviour guaranteed assuming i dont invoke flush() explicitly? If so, how is <jsp:forward> different from RequestDispathcer forward() in this regard?

Cheers,
Arvind

Hi,

There is no difference in the Requestdispatcher and the jsp forward method. The response is commited means all the headers are written to the client. You can do explicilty by using flushBuffer, flush, or reset on the response. The container can implicitly commit the response if the buffer is full.

Thanks

Going by your words, the following HFSF quote cannot be guaranteed. Isnt it?
