AWS redirect in Load Balancer to work with POST and PUT

Question

I want to do something similar to this: Create AWS Application Load Balancer Rule which trim off request's prefix without using additional reverse proxy like nginx, httpd

Using AWS Load balancer, to redirect traffic from URL say /foo to /bar like this:

But only GET requests are routed correctly and POST,PUT,etc get routed as GET so I'm getting an error because my controller doesn't have those GET methods.

Is there a way to do this with AWS load balancer?

The question I linked is from 2016 so I was hoping something has changed in 5 years.

The redirect you show is telling the browser to make a new request to a different URL; it is the browser (following the HTTP standard) which is deciding to make that a GET request. — IMSoP, Jan 20 '21 at 19:06

In case someone is using a client written in Golang, this is why redirected POST requests end up as GET on the server side:

In the section in which you define the condition you have to specify the http method, otherwise it will consider GET as default.

Example for the OPTIONS HTTP calls

You can use /* in the IF section with a path as a condition.

For example, IF /* THEN Redirect to.

Additionally, you can use one of more condition in the IF section such as host-header, http-request-method, query-string, source-ip

then all traffic will be redirected to that, I have more conditions there it's not the only one. – shinzou Jan 28 '21 at 14:21
You can add multiple rules in that case and multiple conditions for each rule. – Skywalker Jan 29 '21 at 01:02
How can I do that? – shinzou Jan 29 '21 at 14:57
You can refer to [this](https://aws.amazon.com/blogs/aws/new-advanced-request-routing-for-aws-application-load-balancers/) blog. Aggregate these cases according to requirement. – Skywalker Jan 29 '21 at 15:12
