Say it like this
- Set up a proxy server
- Route traffic through a proxy
- Use a proxy for caching
- Configure a reverse proxy
- Proxy in front of the API
Use it at work
Networking
- Our requests go through a proxy.
- Set the proxy in your environment variables.
Debugging
- The proxy is blocking the API call.
- Is the proxy timing out?
Data
- We use sign-ups as a proxy for interest.
- Page views are a weak proxy for value.
Don't say this
Proxy is typically a noun (the server/service), not a verb. You route requests 'through' or 'via' a proxy, rather than 'proxy' something.

More about proxy
Real examples(3)
- in a standup
"We deployed a new reverse proxy yesterday to handle the increased load during peak hours."
- in a code review
"This endpoint should go through our API proxy to enforce rate limiting before reaching the backend."
- in a team meeting
"We're implementing a forward proxy to monitor and log all external API calls made by our services."
More mistakes(2)
Handle with care. Avoid confusing 'proxy' (the intermediary server/service) with 'proxy pattern' (the design pattern). Also do not use 'proxy' to mean 'representative person' in technical contexts — stick to the networking/software meaning.
- ✕Can you proxy for me in the meeting?✓Can you represent me in the meeting? / Can you cover that task for me?
In technical English, 'proxy' refers only to network intermediaries, not to people acting as representatives.
- ✕The proxy will directly connect to the server.✓The client will connect to the proxy, which then connects to the server.
A proxy does not directly connect; it acts as an intermediary between two parties.
Other forms(3)
- proxy noun
"The proxy server caches responses to reduce latency."

Often used with(6)
- reverse proxy · A proxy that sits in front of backend servers to handle incoming client requests

Questions(4)
- What is the difference between a forward proxy and a reverse proxy?
- A forward proxy sits between clients and the internet, controlling outgoing traffic from internal networks. A reverse proxy sits between clients and backend servers, handling incoming requests and distributing them to backend services. Forward proxies protect internal users; reverse proxies protect and manage backend servers.
- Why would a company use a proxy?
- Companies use proxies for several reasons: to improve performance through caching, to enhance security by filtering requests, to mask client IP addresses for privacy, to implement rate limiting and access control, or to distribute traffic across multiple servers using load balancing.
- Is proxy formal or informal in tech contexts?
- Proxy is neutral and professional. It is used equally in formal documentation, code reviews, architectural discussions, and casual team conversations. It is standard technical terminology, not slang.
- Can I use proxy as a verb in technical English?
- In standard technical English, proxy is primarily a noun. You do not typically 'proxy' something; instead, you 'route traffic through a proxy' or 'configure a proxy.' However, in some legacy codebases or documentation, you might see 'proxy' used as a verb in specific contexts like the Proxy design pattern, but this is less common in everyday speech.
