Client is throwing `READ` error when requesting healthy HTTP endpoints.

I am having trouble to consume endpoints of Ollama.app, while curl and debug utilities like Postman are working just fine.

It looks like I am not alone. https://github.com/yhirose/cpp-httplib/issues/1379

OK. If you think it's the same as #1379, I'll close it.

This seems to be different from #1379. So I reopen this and add 'bug' label.

I found the reason why it fails. The default read timeout value (CPPHTTPLIB_READ_TIMEOUT_SECOND) is 5 seconds. Since some requests like "what is the sky blue?" takes longer than the read timeout, it fails. When I set the value to 60 (1 minute), it always returns a result.

client.set_read_timeout(60);

I am thinking to change the value of CPPHTTPLIB_READ_TIMEOUT_SECOND to something longer like 300 (5 mins). Anyway, hope this information helps you.
