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.

rt::client::rest::exception

RT::Client::REST::Exception(3pm)			User Contributed Perl Documentation			  RT::Client::REST::Exception(3pm)

NAME

       RT::Client::REST::Exception -- exceptions thrown by RT::Client::REST methods.

DESCRIPTION

       These are exceptions that are thrown by various RT::Client::REST methods.

EXCEPTION HIERARCHY

       RT::Client::REST::Exception
	 This exception is virtual -- it is never thrown.  It is used to group all the exceptions in this category.

	 RT::Client::REST::OddNumberOfArgumentsException
	   This means that the method you called wants key-value pairs.

	 RT::Client::REST::InvaildObjectTypeException
	   Thrown when you specify an invalid type to "show()", "edit()", or "search()" methods.

	 RT::Client::REST::RequiredAttributeUnsetException
	   An operation failed because a required attribute was not set in the object.

	 RT::Client::REST::MalformedRTResponseException
	   RT server sent response that we cannot parse.  This may very well mean a bug in this client, so if you get this exception, some debug
	   information mailed to the author would be appreciated.

	 RT::Client::REST::InvalidParameterValueException
	   Invalid value for comments, link types, object IDs, etc.

	 RT::Client::REST::CannotReadAttachmentException
	   Cannot read attachment (thrown from methods "comment()" and "correspond").

	 RT::Client::REST::RTException
	   This is a virtual exception and is never thrown.  It is used to group exceptions thrown because RT server returns an error.

	   RT::Client::REST::ObjectNotFoundException
	     One or more of the specified objects was not found.

	   RT::Client::REST::AuthenticationFailureException
	     Incorrect username or password.

	   RT::Client::REST::UpdateException
	     This is a virtual exception.  It is used to group exceptions thrown when RT server returns an error trying to update an object.

	     RT::Client::REST::CouldNotSetAttributeException
	       For one or another reason, attribute could not be updated with the new value.

	     RT::Client::REST::InvalidEmailAddressException
	       Invalid e-mail address specified.

	     RT::Client::REST::AlreadyCurrentValueException
	       The attribute you are trying to update already has this value.  I do not know why RT insists on treating this as an exception, but
	       since it does so, so should the client.	You can probably safely catch and throw away this exception in your code.

	     RT::Client::REST::ImmutableFieldException
	       Trying to update an immutable field (such as "last_updated", for example).

	     RT::Client::REST::IllegalValueException
	       Illegal value for attribute was specified.

	   RT::Client::REST::UnknownCustomFieldException
	     Unknown custom field was specified in the request.

	   RT::Client::REST::InvalidQueryException
	     Server could not parse the search query.

	   RT::Client::REST::UnauthorizedActionException
	     You are not authorized to perform this action.

	   RT::Client::REST::AlreadyTicketOwnerException
	     The owner you are trying to assign to a ticket is already the owner.  This exception is usually thrown by methods "take()", "untake",
	     and "steal", if the operation is a noop.

	   RT::Client::REST::RequestTimedOutException
	     Request timed out.

	   RT::Client::REST::UnknownRTException
	     Some other RT exception that the driver cannot recognize.

METHODS

       _get_exception_class
	 Figure out exception class based on content returned by RT.

       _rt_content_to_exception
	 Translate error string returned by RT server into an exception object ready to be thrown.

SEE ALSO

       Exception::Class, RT::Client::REST.
