client.requests
INTEGER, read-only.
Available inall subroutines.
Tracks the number of requests received by Varnish over a persistent connection. Over an HTTP/2 connection, tracks the number of multiplexed requests.
With HTTP/1.1, persistent connections are the default. A persistent connection is one that remains open for a period of time and can be reused for \"several requests\", saving the need for a new TCP handshake for every request.
With HTTP/2, concurrent requests are allowed over a single connection, which is called multiplexing.
Try it out
client.requests is used in the following code examples. Examples apply VCL to real-world use cases and can be deployed as they are, or adapted for your own service. See the full list of code examples for more inspiration.
Click RUN on a sample below to provision a Fastly service, execute the code on Fastly, and see how the function behaves.
Throttling per country over configurable time periods
Adjust the maximum TCP socket pacing for connections at peak times of day in busy regions.
