+- Deploy the nginx proxy cache for /rest requests on CGSpace
+  - I had tested this last week on DSpace Test
+  - By my counts on CGSpace yesterday (Sunday, a busy day for the REST API), we had 5,654 URLs that were requested more than twice, and it tails off after that towards two, three, four, etc:
+
+```console
+# awk '{print $7}' /var/log/nginx/rest.log.1 | grep -v retrieve | sort | uniq -c | awk '$1 > 1' | wc -l
+5654
+# awk '{print $7}' /var/log/nginx/rest.log.1 | grep -v retrieve | sort | uniq -c | awk '$1 == 2' | wc -l
+4710
+# awk '{print $7}' /var/log/nginx/rest.log.1 | grep -v retrieve | sort | uniq -c | awk '$1 == 3' | wc -l
+814
+# awk '{print $7}' /var/log/nginx/rest.log.1 | grep -v retrieve | sort | uniq -c | awk '$1 == 4' | wc -l
+86
+# awk '{print $7}' /var/log/nginx/rest.log.1 | grep -v retrieve | sort | uniq -c | awk '$1 == 5' | wc -l

+```
+
+- For now I guess requests that were done two or three times by different clients will be cached and that's a win, and I expect more and more REST API activity soon when initiatives and One CGIAR stuff picks up
