Here is what I have used to access proxy autocomplete google places requests through local host on an installation of Apache including ssl support (version 2.2 for windows). Edit the apache file httpd.conf. Depending on your distribution and Apache version you may have to check if modproxyconnect and modproxyhttp are loaded as well. The directives for enabling SSL proxy support are in modssl. Step 1 - Create a HttpHost object Instantiate the HttpHost class of the org.apache.http package by passing a string parameter representing the name of the proxy host, (from which you need the requests to be sent) to its constructor. //Creating an HttpHost object for proxy HttpHost proxyHost = new HttpHost ('localhost').

Proxy Support How-To

Introduction

Using standard configurations of Tomcat, web applications can ask forthe server name and port number to which the request was directed forprocessing. When Tomcat is running standalone with theHTTP/1.1 Connector, it will generallyreport the server name specified in the request, and the port number onwhich the Connector is listening. The servlet APIcalls of interest, for this purpose, are:

• ServletRequest.getServerName(): Returns the host name of the server to which the request was sent.
• ServletRequest.getServerPort(): Returns the port number of the server to which the request was sent.
• ServletRequest.getLocalName(): Returns the host name of the Internet Protocol (IP) interface on which the request was received.
• ServletRequest.getLocalPort(): Returns the Internet Protocol (IP) port number of the interface on which the request was received.

When you are running behind a proxy server (or a web server that isconfigured to behave like a proxy server), you will sometimes prefer tomanage the values returned by these calls. In particular, you willgenerally want the port number to reflect that specified in the originalrequest, not the one on which the Connector itself islistening. You can use the proxyName and proxyPortattributes on the <Connector> element to configurethese values.

Proxy support can take many forms. The following sections describeproxy configurations for several common cases.

Apache httpd Proxy Support

Apache httpd 1.3 and later versions support an optional module(mod_proxy) that configures the web server to act as a proxyserver. This can be used to forward requests for a particular web applicationto a Tomcat instance, without having to configure a web connector such asmod_jk. To accomplish this, you need to perform the followingtasks:

1. Configure your copy of Apache so that it includes the mod_proxy module. If you are building from source, the easiest way to do this is to include the --enable-module=proxy directive on the ./configure command line.

2. If not already added for you, make sure that you are loading the mod_proxy module at Apache startup time, by using the following directives in your httpd.conf file:

3. Include two directives in your httpd.conf file for each web application that you wish to forward to Tomcat. For example, to forward an application at context path /myapp:

   which tells Apache to forward URLs of the form http://localhost/myapp/* to the Tomcat connector listening on port 8081.

4. Configure your copy of Tomcat to include a special <Connector> element, with appropriate proxy settings, for example:

   which will cause servlets inside this web application to think that all proxied requests were directed to www.mycompany.com on port 80.

5. It is legal to omit the proxyName attribute from the <Connector> element. If you do so, the value returned by request.getServerName() will by the host name on which Tomcat is running. In the example above, it would be localhost.

6. If you also have a <Connector> listening on port 8080 (nested within the same Service element), the requests to either port will share the same set of virtual hosts and web applications.

7. You might wish to use the IP filtering features of your operating system to restrict connections to port 8081 (in this example) to be allowed only from the server that is running Apache.

8. Alternatively, you can set up a series of web applications that are only available via proxying, as follows:

   • Configure another <Service> that contains only a <Connector> for the proxy port.
   • Configure appropriate Engine, Host, and Context elements for the virtual hosts and web applications accessible via proxying.
   • Optionally, protect port 8081 with IP filters as described earlier.

9. When requests are proxied by Apache, the web server will be recording these requests in its access log. Therefore, you will generally want to disable any access logging performed by Tomcat itself.

When requests are proxied in this manner, all requestsfor the configured web applications will be processed by Tomcat (includingrequests for static content). You can improve performance by using themod_jk web connector instead of mod_proxy.mod_jk can be configured so that the web server serves staticcontent that is not processed by filters or security constraints definedwithin the web application's deployment descriptor(/WEB-INF/web.xml).

A Proxy server is an intermediary server between the client and the internet. Proxy servers offer the following basic functionalities −

• Firewall and network data filtering

• Network connection sharing

• Data caching

Using HttpClient library, you can send a HTTP request using a proxy. Follow the steps given below −

Step 1 - Create a HttpHost object

Instantiate the HttpHost class of the org.apache.http package by passing a string parameter representing the name of the proxy host, (from which you need the requests to be sent) to its constructor.

In the same way, create another HttpHost object to represent the target host to which requests need to be sent.

Step 2 - Create an HttpRoutePlanner object

The HttpRoutePlanner interface computes a route to a specified host. Create an object of this interface by instantiating the DefaultProxyRoutePlanner class, an implementation of this interface. As a parameter to its constructor, pass the above created proxy host −

Step 3 - Set the route planner to a client builder

Using the custom() method of the HttpClients class, create a HttpClientBuilder object and, to this object set the route planner created above, using the setRoutePlanner() method.

Step 4 - Build the CloseableHttpClient object

Build the CloseableHttpClient object by calling the build() method.

Step 5 - Create a HttpGetobject

Create a HTTP GET request by instantiating the HttpGet class.

Step 6 - Execute the request

One of the variants of the execute() method accepts an HttpHost and HttpRequest objects and executes the request. Execute the request using this method −

Example

Following example demonstrates how to send a HTTP request to a server via proxy. In thisexample, we are sending a HTTP GET request to google.com via localhost. We have printed the headers of the response and the body of the response.

Output

On executing, the above program generates the following output −
