C Socket Client/Server Fork Loop
Hello people.

I'm trying to do something like a search engine.
Server runs in the background by using ./server & which has data from a textfile stored in an array.
Client then runs by using ./client
It will then prompt "Search for:"

For example, if I searched for Products called Instant Noodles
Server will return me result:
Product : Instant Noodle
Price : $10
If there's no such product, it will return "No such product"

I've already done it up to here.
Problem is, I want to make the client loop, after it finishes searching for a product, "Search for:" will appear again. The socket connection will only end when the user types in "end"
I can make it end by typing "end", but not the loop for search.
How can I do this?
I'm currently using the fork() command to handle multiple clients.

Thanks in advance.

net::server::multitype

Net::Server::MultiType(3pm)				User Contributed Perl Documentation			       Net::Server::MultiType(3pm)

NAME

       Net::Server::MultiType - Net::Server personality

SYNOPSIS

	   use base qw(Net::Server::MultiType);

	   sub process_request {
	       #...code...
	   }

	   my @types = qw(PreFork Fork Single);

	   Net::Server::MultiType->run(server_type => @types);

DESCRIPTION

       Please read the pod on Net::Server first.  This module is a personality, or extension, or sub class, of the Net::Server module.

       This personality is intended to allow for easy use of multiple Net::Server personalities.  Given a list of server types,
       Net::Server::MultiType will require one at a time until it finds one that is installed on the system.  It then adds that package to its
       @ISA, thus inheriting the methods of that personality.

ARGUMENTS

       In addition to the command line arguments of the Net::Server base class, Net::Server::MultiType contains one other configurable parameter.

	   Key		     Value	      Default
	   server_type	     'server_type'    'Single'

       server_type
	   May be called many times to build up an array or possible server_types.  At execution, Net::Server::MultiType will find the first
	   available one and then inherit the methods of that personality

CONFIGURATION FILE

       "Net::Server::MultiType" allows for the use of a configuration file to read in server parameters.  The format of this conf file is simple
       key value pairs.  Comments and white space are ignored.
