      Description

      1. Create a proxy repository from Nexus Repo 2.14.20 to the npm registry.
      2. Create a proxy repository in Nexus Repo 3.34.1 to the proxy you just created in NXRM 2.
      3. Request metadata through the Nexus Repo 3 proxy twice.
      4. Observe that both requests get a 200 response along with full content.

      127.0.0.1 - - [23/Sep/2021:10:48:36 -0500] "GET /nexus/content/repositories/npm-proxy/lodash HTTP/1.1" 200 213932 16
      127.0.0.1 - - [23/Sep/2021:10:48:43 -0500] "GET /nexus/content/repositories/npm-proxy/lodash HTTP/1.1" 200 213932 12

      This shouldn't be the case, Nexus Repo 3 is sending a conditional get request:

      Retrieval of npm metadata in Nexus Repo 2.x can be very expensive due to the need to construct a potentially large JSON object in memory.

      Expected: Conditional get requests using the If-Modified-Since header should work in Nexus Repo 2 npm repositories. This should be tested against hosted, proxy, and group repositories.
