I spend hour trying to create custom error pages with this cats, and finally found this gist: https://gist.github.com/mjmeyer/6cf8d3c1199d028f0921
Works awesome for me, all what you need is do download it to your nginx directory:

cd /etc/nginx/snippets && sudo wget https://gist.githubusercontent.com/mjmeyer/6cf8d3c1199d028f0921/raw/1866fb0bc75dcd8c0699bccf499bae2cb15dca17/http-cat-error-pages.conf

Then add this lines to your "server" block:

include snippets/http-cat-error-pages.conf
resolver 1.1.1.1

I think this should be added to README, as I think that I was not the only one who tried to do this.

Awesome stuff! Love Cats ❤️

We have created a collection out of all these requests and below is the link for the same:

https://documenter.getpostman.com/view/6034746/SzzrWt5f

Click on "Run in Postman" and it will import all of these directly to the users applications and one can use it. However, the interesting point here is - you can create an "Embed button" from the same and include it to your WebPage. Below documentation should help you on this:

https://learning.postman.com/docs/postman-for-publishers/run-in-postman/creating-run-button

Example:

I'll be glad to assist you with this if required 👍

current is

<a href="/510"><li class="status" style="background-image:url(/510)"><span>510</span></li></a> 
<a href="/511"><li class="status" style="background-image:url(/511)"><span>511</span> 
<a href="/599"><li class="status" style="background-image:url(/599)"><span>599</span></li></a>
</li></a>
</ul>

probably should be

<a href="/510"><li class="status" style="background-image:url(/510)"><span>510</span></li></a> 
<a href="/511"><li class="status" style="background-image:url(/511)"><span>511</span></li></a>
<a href="/599"><li class="status" style="background-image:url(/599)"><span>599</span></li></a>
</ul>

Trying to replicate the api behavior of the images.

Is it possible to share what the nginx.conf looks like that provides this feature?

Thanks!

it'd be useful to request https://http.cat/401 with either "Accept: application/json" or /401.json to get a response similar to

{ 
 "code": 401
 "description": "Unauthorized"
}

mostly I am looking for a data source for an irc bot to respond to "!http 401".

A status code of something like that

Hello maintainer of this cute repository!

Me and @richardcsantana noticed that 425 http code, according with RFC is about "Too early", but in the site it is represented by "Unordered collection"

RFC 📚
Page 🐱

Count with us if you need some support to fix it. We found this image that we judge as appropriate.

Here's a custom one I made to hang on my door while I'm on vacation: it's inverted so it's good for printing! :D

Missing cat for status code 521 Web Server Down commonly used by the cloud flare service

Hey! 👋

The image for code (HTTP) 203 Non-Authoritative Information is missing

I suggest something like http://i.imgur.com/mWhyo.jpg

The link at the bottom of the page is still “Versió Català”.

https://http.cat/dog should be aliased to https://http.cat/418

People are getting the "Your connection is not private" message on Chrome. Thank you!

This is literally the best website ever. Please let me send you something for making me happy. 🍕

Details of this status code can be found here
This is pretty relevant at the moment due to the Lets Encrypt CA expiry

It would be very cool and absolutely in-line with the meme-y nature of the page to support the 7xx line of http status codes.
A RFC draft can be found on GitHub.

Here's a list of the ones I've found that aren't supported:

IIS

• 440 Login Timeout
• 449 Retry With

nginx

• 495 SSL Certificate Error
• 496 SSL Certificate Required
• 497 HTTP request sent to HTTPS port (idea: maybe have an image of a cat trying to go through a dog door for this?) (Added by #124)

Cloudflare

• 520 Web Server Returned an Unknown Error
• 521 Web Server Is Down
• 522 Connection Timed Out
• 523 Origin Is Unreachable
• 524 A Timeout Occurred
• 525 SSL Handshake Failed
• 526 Invalid SSL Certificate
• 527 Railgun Error
• 530

AWS ELB

• 460
• 463 (maybe an image of 30 cats trying to do into a box at once?)
• 561 Unauthorized

Note: I got all these from The Wikipedia Page

We have a missing status (102) I think we could do a cat with a loading icon on his head?
Update : creating the image

498 Invalid Token

Title says all, I'll try to make it a pull request in time.
Suggested picture for now (still needs the border and text):

Love this project if dogs are also there :)

For example, 400.jpeg could be compressed from 120kb to about 50kb, nearly 60% smaller, without noticeable quality loss. It could save some bandwidth both for https://http.cat and for people who reference those cute cat images.

Take a look at: https://tinypng.com/ , they are good at compressing images, and have an API for that. Their API is free for the first 500 images in a month, it's quite enough for https://http.cat I think.

If you are interested, I can open a pull request.

I shared the url with community devs and got immediate pushback from those who use screen readers to navigate the internet.

• Images do not have useful alt text
• Status code not in body in text; no indication of page purpose.

I believe the pages do not meet minimal Web Content Accessibility Guidelines 2.1, but should be able to to get there very easily. It would also prepare the project for automated language translation.

This project is very interesting!
Thank for your hard work.

Hey! 👋

The code description for 413 is Payload Too Large (RFC).
On the homepage is correct, but the picture says Request Entity Too Large.

Cheers! ✌️

I thought making a request to https://http.cat/404 would return a page with an actual 404 status code... 🤔

Isn't that the idea for this site? or is it just the images?

Please enable IPv6 support on http.cat.

I see it is being hosted on DigitalOcean. Instructions to enable: https://www.digitalocean.com/docs/networking/ipv6/how-to/enable/

Thanks!

Hello Is Possible To Add A Beaker Peer To Peer Version Because You Add For Brave Payment And I Not To See A Most Or Some Website With P2P In Beaker Browser

Instruction ::::: https://github.com/beakerbrowser/beaker/wiki/Authenticated-Dat-URLs-and-HTTPS-to-Dat-Discovery

Thanks You In The Answer

501 Not Implemented is... not implemented... 😆

For some reason, this is what is being sent to the client on https://http.cat/404:

Not the 404 I expected.. 😕

[...] target resource has been assigned a new permanent URI and any future references to this resource ought to use one of the enclosed URIs.

https://tools.ietf.org/html/rfc7538

Or just reuse https://http.cat/301 because it's almost the same?

Hey, there is no image for 525: SSL handshake failed

Some suggestions to be used:

UPD: Links to Image1 and image2

The "resource is unavailable due to an external legal request" status code implemented by Github is missing.

The "Enhance Your Calm" status code implemented by Twitter is missing.

https://http.cat/407 = 404

https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/407

Is he okay? http.cat/499

The image is of the Schrödinger's cat thought-experiment, wherein the cat is alive and dead at the same time (sort of) - i.e. it is multi-status, aka HTTP 207. HTTP 303 on the other hand is a type of redirect, to which Schrödinger's cat does not have any obvious relevance.

407 Proxy Authentication Required
Similar to 401 Unauthorized, but it indicates that the client needs to authenticate itself in order to use a proxy.

It would be nice if https://http.cat/420?lang=cat returned something similar to:

There's currently no image for the 205 Reset Content status code. I don't currently have any suggestions for a picture to use, but I'll keep an eye out.

The 504 cat is missing even though it is available on flickr.

Is there a problem with copyright or are pull requests welcome?
