httpmethod.java

这是linux下ssl vpn的实现程序

package com.maverick.http;

import java.io.IOException;

import java.io.InputStream;
import java.util.Hashtable;
import java.util.Vector;

  }

  public String getName() {
      return name;
  }

  }

  public void setParameter(String name, String value) {
      if(!parameters.containsKey(name))
          parameters.put(name, new Vector());

  }

      } else

  }

  public HttpResponse execute(HttpRequest request, HttpConnection con) throws IOException {
