Add and Remove Prefix

Add or remove URL path prefixes when proxying requests in the Serverless API Gateway. Rewrite or strip path segments before forwarding to upstream servers.

{
    ...
    "servers": [
        {   
            "alias": "prefixing",
            "url": "https://sub.serverlessapigw.com/prefix/"
        },
        ...
    ],
    ...
    "paths": [
        {
            "method": "GET",
            "path": "/{.+}",
            "integration": {
                "type": "http_proxy",
                "server": "prefixing"
            }
        },
```

With the above configuration, any GET request to the API will be proxied to 'https://sub.serverlessapigw.com/prefix'.

For example: GET https://api.yourdomain.com/path will be proxied to GET https://sub.serverlessapigw.com/prefix/path.

This method can also be used to remove a portion of the path from the beginning:

{
    ...
    "servers": [
        {   
            "alias": "prefixing",
            "url": "https://sub.serverlessapigw.com"
        },
        ...
    ],
    ...
    "paths": [
        {
            "method": "GET",
            "path": "/prefix/{.+}",
            "integration": {
                "type": "http_proxy",
                "server": "prefixing"
            }
        },
```

With this configuration, GET https://api.yourdomain.com/prefix/path will be proxied to GET https://sub.serverlessapigw.com/path.
