| Demonstrate the basic functions of the URL rewrite mediator |
| </p> |
| </subsection> |
| <subsection name="Pre-requisites"> |
| <p> |
| <ul> |
| <li> |
| Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2 |
| </li> |
| <li> |
| Start Synapse using the configuration numbered 450 (repository/conf/sample/synapse_sample_450.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 450<br/> |
| Windows: synapse.bat -sample 450 |
| </div> |
| </li> |
| </ul> |
| </p> |

| <subsection name="Executing the Client"> |
| <p> |
| URL rewrite mediator can be used to modify the 'To' header of a request based on |
| one or more user defined URL rewrite rules. A rewrite rule could be a |
| plain rewrite instruction or a conditional instruction. In this sample we use a |
| plain, unconidtional rewrite rule which simply replaces the string 'soap' with |
| 'services' in the 'To' header. |
| </p> |
| <p> |
| Invoke the sample client as follows to try this out. |
| </p> |
| <div class="command">ant stockquote -Dtrpurl=http://localhost:8280 -Daddurl=http://localhost:9000/soap/SimpleStockQuoteService</div> |
| <p> |
| Note that the address URL of the client request contains the context 'soap'. But |
| in the Axis2 server all the services are deployed under a context named 'services' |
| by default. Synapse will rewrite the To header of the request by replacing the |
| 'soap' context with 'services. Hence the request will be delivered to the Axis2 |
| server and the Axis2 client will receive a valid response. |
