IRule for URL redirect

We need to configure an IRule in F5 for redirecting URL. The source URL will have an object id in its URI which we need to fetch and append it in the destination URL.

 

Source URL can come in two formats as shown below and object id in it is highlighted in bold.

http://mytest.mytest.com/webtop/drl/objectId/0900e6cc81095ef9/chronicleId/0900e6cc81095ef9

 

 

We need to fetch the object id (0900e6cc814a810c and 0900e6cc81095ef9) from above sample URL and append it in destination redirect URL as shown below

 

https://redirect.mytest.com/api/LinkServ?objectID=”WebtopObject ID”

 

https://redirect.mytest.com/api/LinkServ?objectID=”0900e6cc814a810c ”

    You can use the getfield option to extract that objectid, something like, if there are multiple other hosts coming to this setup, you can add host condition and then take action too.

    ltm rule objectid_redirect {
when HTTP_REQUEST {
set uri [HTTP::uri]
set id [getfield $uri "/" 5]
log local0. "ObjectID is $id"
HTTP::redirect https://redirect.mytest.com/api/LinkServ?objectID=$id
}
}

    Hope it helps. Test & update us.
