I know answering this topic is like digging a corpse from its grave since it's really old but I'd like to share my experience IMHO, the best way is to wrap your request and apply your replacement . it's more portable than other ways. here is a java sample

public class FarsiRequestWrapper extends HttpServletRequestWrapper{

@Override
public String getParameter(String name) {
    String parameterValue = super.getParameter(name);
    parameterValue.replace("ی", "ي");       
    parameterValue.replace("\\s+", " ");
    parameterValue.replace("ک","ک");
    return parameter.trim();
}

}

then you only need to setup a filter servlet

public class FarsiFilter implements Filter{

public void doFilter(ServletRequest request, ServletResponse response,
        FilterChain chain) throws IOException, ServletException {

    HttpServletRequest req = (HttpServletRequest) request;
    FarsiRequestWrapper rw = new FarsiRequestWrapper(req);
    chain.doFilter(rw, response);
}

} although this approach only works in Java, I found it simpler and better.
