Proxy Questions

Question

I have two questions regarding HTTP proxy servers:
1) For redirection codes such as 301, is it more common for the proxy server or the web client to handle the redirection and send another request?
2) Regarding downloading embedded objects, I would appreciate it if anyone could let me know what would be the quickest or easiest classes and methods to use to read and write binary files. The following block was used for downloading base pages. I plan on making an else statement with similar code (but for downloading and writing binary instead of text)
/** this code is in a HTTP proxy server
contentType is a String with the type from the Content-Type header field
FromOServer is a BufferedReader that reads from the original server
ToWClient is a DataOutputStream that writes to the web client using the proxy
if (contentType.equals("text")) {
response = FromOServer.readLine();
while (response != null) {
ToWClient.writeBytes(response + "\r\n");
response = FromOServer.readLine();
Please tell me if you have suggestions for which classes and methods would be either easiest or quickest for doing the same thing above except for binary files instead of Strings of text.

checkout the reply '3'. That explains how to add a regex to block urls.
but why do you want to deny port 89? (if your requirement is that you want to block a 'local' port -- as opposed to a remote port, -- what you need might be a firewall rather than a proxy.)
