greetings everyone!

does anyone have ever do filtering the web content using java app?
I thought that this could be used, when we apply some socketserver into our localhost itself.
And with another socket to connect to the real web domain (address).

(take note: that our machine is connected to the internet line).

And...
The problem arose when the bytes received from the real web domain (address) translated from
inputstream... which makes the loading ... output appearance at our browser seems slow.

Does anyone may give me a bit clue to overcome this problem?

* NB: Sorry, i didnt mean to duplicate the thread (from Socket section).

You might try Googling "proxy" for some ideas and source code.

The HTTP protocol has become complicated over the years in favor of higher throughput. I suspect that you're doing one of the following:
  • not making use of stay-open connections (i.e. re-connecting each time)

  • not handling "chunking" properly

  • waiting for all the bytes to arrive before outputting any filtered data to the client

  • you have a very inefficient filtering algorithm

  • you are not using threads for parallel processing of multiple streams.

well, thanks for the respond, Carey Brown.
I did searching through Google. And I already did, get my app running.

when you said,
not making use of stay-open connections (i.e. re-connecting each time)
you are not using threads for parallel processing of multiple streams.

I'm using a Socket instances within a Thread class.

and,
you have a very inefficient filtering algorithm
waiting for all the bytes to arrive before outputting any filtered data to the client


That's rite, my algorithm is inefficient. Probably yes. That's why I need some evaluation.
but is it okay If I posted up the
source code I written here? (it's just 2 class(file) only).

If this was my problem, I'd start with an existing proxy solution -such as Muffin, but possibly a bit less dated- and would try to adapt it to my purposes.
