Intercept http traffic and change it before sending further

[GoogleCodeExporter]

Implement interceptor plugin. Trigger should be bash scripting.
Script for request and response.

I can't seem to manipulate the request object through the Interceptor. In 
particular I am trying to do the following:

query = request.getURL().getQuery();
query = query.replace("ABC", "DEF");
request.setContent(query.toBytes());

There seems to be an error with the "replace" function.

And query is of type String?
Object used are same as in search scripting.

Last line is also not okey. You should use this approach

Example of response intercept script that do not trigger gui.
It just change response content for wiki main page

///
import org.sandrop.webscarab.model.Request;
import org.sandrop.webscarab.model.Response;
import org.sandrop.webscarab.model.Message;
import org.sandrop.webscarab.model.ConnectionDescriptor;
import org.sandrop.webscarab.model.HttpUrl;
import android.util.Log;

                result = false;
                boolean LOGD = true;
                String  TAG = "scriptInterceptor";
                boolean changeResponse = false;
                // sending request to server to get response
                ConnectionDescriptor cr = request.getConnectionDescriptor();
                if (cr != null){
                    if (LOGD) Log.d(TAG, "Connection data from: " + cr.getNamespace() + " " + cr.getId());
                }

                HttpUrl reqUrl = request.getURL();
                if (reqUrl != null && reqUrl.getHost() != null && reqUrl.getPath() != null &&
                        (reqUrl.getHost().equals("en.wikipedia.org") || reqUrl.getHost().equals("en.m.wikipedia.org")) && 
                        reqUrl.getPath().equals("/wiki/Main_Page")){
                    changeResponse = true; 
                }

                // should we change response before goes to client
                if (changeResponse && response != null && response.getStatus().equals("200")){
                    byte[] responseContentByteArr = response.getContent();
                    if (responseContentByteArr != null){
                        String responseContentStr = new String (responseContentByteArr);
                        String changedResponse = responseContentStr.replace("<title>Wikipedia, the free encyclopedia</title>", "<title>SandroProxy: Wikipedia, the free encyclopedia </title>");
                        response.setContent(changedResponse.getBytes());
                        if (LOGD) Log.d(TAG, "Response content modified by plugin");
                    }
                }
                return false;
