ProxyFilter
If a filter-mapping url-pattern in the web.xml file matches the requested URL, then the request will be sent to the ProxyFilter, which will in turn forward the request. A few searches and replaces are performed on the response to re-write URLs in response document.
The proxy point is hard-coded in:
/src/gov/loc/ndmso/ProxyFilter/ProxyFilter.java
The searches and replaces are hard-coded in /src/gov/loc/ndmso/ProxyFilter/RequestProxy.java
Install the built jar to the WEB-INF/lib directory.
Add to web.xml (after description but before listener or servlets):
<filter>
<filter-name>ProxyFilter</filter-name>
<filter-class>gov.loc.ndmso.proxyfilter.ProxyFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>ProxyFilter</filter-name>
<url-pattern>/lcds/*</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>ProxyFilter</filter-name>
<url-pattern>/static/*</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>ProxyFilter</filter-name>
<url-pattern>/media/*</url-pattern>
</filter-mapping>
