Go-http-client

Gopherus hurryus

Vagantes, the strays. Script or library.

A joke about the drawing A gopher, on the go.

The line above plays on the name. It says nothing about how the bot behaves: everything below is read from the request log, for today and the 29 days before it, by UTC date.

Alignment

Insufficient data. A judgement needs at least 200 requests and 5 sessions in the trailing 30 days. This one would rest on all its sessions: 1 request in 1 session over the trailing 30 days.

How the score is worked out, and the count behind every input, is on the Census page.

Who runs it, and how that is checked

Who runs it: a Go program
A user-agent string it sends: Go-http-client/2.0 As commonly seen in server logs. Not yet checked against the operator’s documentation.
What it says it is for: Go-http-client is what a program written in Go sends when it uses the language’s built-in web client and nobody sets a name.

Everything above is a claim: the operator’s own account where it has published one, and a third party’s where it has not. This site has not tested it. What the bot has done is in the sections below, read from the request log.

No operator. Anyone can run it, so there is no identity for Customs to check, and its sessions are filed as undeclared.

The name it is matched on

A request is filed under this species when its user-agent string contains the product name Go-http-client as a whole word, in any mix of capitals. Where a string holds more than one product name, the longest wins, and a named bot wins over a library it is built on.

How to address this bot in robots.txt

A group in robots.txt addresses this bot by the line:

User-agent: Go-http-client

An example group. The path is a placeholder.

User-agent: Go-http-client
Disallow: /a-path/
Allow: /a-path/one-page

This is reference, not advice. Systema Machinae is not a bot-blocking product.

This site’s own robots.txt does not name it. The group for every bot applies.

Landings

1 landing in the trailing 30 days. A landing is the first request of a session.

Customs
