We now allow multiple OPDS feeds to be pre-defined and displayed on the homepage. As a result we need to pass the feed navigation URLs via query parameter rather than a subpath which would only support proxying to a single OPDS feed. The feed is passed via the q= query parameter and any relative links from the OPDS XML are resolved to a complete URL with domain / scheme. We also check the "Content-Type" header in the response received from the OPDS feed to determine whether to parse an OPDS catalog or just proxy the raw response back (images / files).
