I think it would be better to not use redirect and just use the header_rewrite to do the redirect and set the cache-control header.  Here is an example:

Config:
[bcall@homer ~]$ tail -1 /usr/local/etc/trafficserver/remap.config
#redirect http://www.google.com/ http://www.yahoo.com/ @plugin=header_rewrite.so @pparam=/usr/local/etc/trafficserver/foo.config
[bcall@homer ~]$ cat /usr/local/etc/trafficserver/foo.config
set-redirect 302 http://www.yahoo.com/%{PATH}

cond %{SEND_RESPONSE_HDR_HOOK}
rm-header Cache-Control
set-header Cache-Control "max-age=600, public"

Test:
[bcall@homer ~]$ curl -D - -H 'Host: www.google.com' http://127.0.0.1:8080/
HTTP/1.1 302 Redirect
Date: Thu, 17 Nov 2016 03:13:22 GMT
Connection: keep-alive
Server: ATS/7.1.0
Location: http://www.yahoo.com/
Content-Type: text/html
Content-Language: en
Cache-Control: max-age=600, public
Content-Length: 303

I ran a test myself and I don’t know of a way to make the response cacheable.  I assume you would like to set the Cache-Control header to something like max-age=300.  I will talk to a couple other Committers tonight and see if they have any ideas.

This is what I am seeing:
[bcall@homer ~]$ curl -D - -H 'Host: www.google.com' http://127.0.0.1:8080/
HTTP/1.1 301 Redirect
