Reverse proxy (SEO use)
In SEO, a reverse proxy serves content hosted elsewhere under a single domain: visitors and search engines see site.com/resources/, while a separate infrastructure responds. It is the technical basis for subfolder-based setups.
In practice
The benefit: attach a high-performing section — blog, documentation, generated pages — without touching the client’s legacy server. Careful configuration is mandatory: clean headers, canonical tags pointing to the public domain, no leaking of origin URLs. The engine sees one unified site; that is precisely the point.
