Asset Redirection

[Leela-Pavan-Kumar]

I have a requirement where if we hit for 'X' asset it has to redirect to 'Y' asset.

How to implement this redirection in AEM.

Hi @Leela-Pavan-Kumar,

You can achieve this using Redirect Manager from ACS Commons:

•  https://adobe-consulting-services.github.io/acs-aem-commons/features/redirect-manager/index.html

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:

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

@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.
