The documentation for proxy_read_timeout is a little vague when it comes to the time parameter.


Examples in this web page indicate that time can be specified as a number followed by a letter. 60s in this example. The reader must assume that 's' means seconds. It is not described anywhere.

Then in another example of a configuration file, proxy_read_timeout is set to 90 with no letter specifying what units 90 represents.


It would be really nice if the documentation for proxy_read_timeout spelled out that "s" means seconds, "m" means minutes, and that if you don't specify the units, then they default to seconds. I'm guessing of course, even now. I wonder if the default units is actually milliseconds.

Thanks for all of your great work!

Units used in various configuration directives, including the proxy_read_timeout directive, are documented in the Configuration file measurement units article.
