@Leela-Pavan-Kumar, in that case you can use one of below solutions:

  • Apache rewrite map - https://httpd.apache.org/docs/current/rewrite/rewritemap.html
  • Redirect Map Manager form ACS Commons - https://adobe-consulting-services.github.io/acs-aem-commons/features/redirect-map-manager/index.html
  • Finally you can write your own Sling Filter. Below is very simple example, that will redirect you from /document/adobe.pdf to /content/dam/wknd/en/adobefile.pdf. I have tested it on clear AEM 6.5.13 - and it works without any issue. Of course you will need to manage list of redirect somehow, but there are many options, e.g. CA Configuration.
    package com.example.filters;
    
    import org.apache.sling.api.SlingHttpServletRequest;
    import org.apache.sling.api.SlingHttpServletResponse;
    import org.apache.sling.api.servlets.HttpConstants;
    import org.apache.sling.engine.EngineConstants;
    import org.osgi.framework.Constants;
    import org.osgi.service.component.annotations.Component;
    
    import javax.servlet.*;
    import java.io.IOException;
    import java.util.HashMap;
    import java.util.Map;
    
    @Component(service = Filter.class, immediate = true, property = {
            EngineConstants.SLING_FILTER_SCOPE + "=" + EngineConstants.FILTER_SCOPE_REQUEST,
            EngineConstants.SLING_FILTER_METHODS + "=" + HttpConstants.METHOD_GET,
            Constants.SERVICE_RANKING + "=" + Integer.MAX_VALUE
    })
    public class RedirectFilter implements Filter {
    
        private Map<String, String> redirectMap = new HashMap<String, String>();
    
        @Override
        public void init(FilterConfig filterConfig) throws ServletException {
            redirectMap.put("/document/adobe.pdf", "/content/dam/wknd/en/adobefile.pdf");
        }
    
        @Override
        public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
            SlingHttpServletRequest slingRequest = (SlingHttpServletRequest) servletRequest;
            SlingHttpServletResponse slingResponse = (SlingHttpServletResponse) servletResponse;
    
            String path = slingRequest.getRequestPathInfo().getResourcePath();
            if (redirectMap.containsKey(slingRequest.getRequestPathInfo().getResourcePath())) {
                slingResponse.sendRedirect(redirectMap.get(path));
                return;
            }
            filterChain.doFilter(servletRequest, servletResponse);
        }
    
        @Override
        public void destroy() {
        }
    }

Hi @Leela-Pavan-Kumar,

You can achieve this using Redirect Manager from ACS Commons:

I did a quick test on AEM 6.5.13 and ACS Commons 5.3.2, and it worked.

This is how my test configuration looks like:

redirect-config.png

So when I hit:

  • localhost:4503/content/dam/we-retail/en/experiences/48-hours-of-wilderness/48-hours-of-wilderness-1.jpg

as a result I am getting:

  • localhost:4503/content/dam/we-retail/en/experiences/skitouring/skitouring-1.jpg

Tired this one @lukasz-m , but here the source needs to be there in our DAM Assets.

 

In our case Asset is not present in our DAM.

 

if we hit

    localhost:4503/document/adobe.pdf

it has to take me to 

    localhost:4503/content/dam/wknd/en/adobefile.pdf
