How can I create the 405 error - http

I need to test 405 error page, but I have no idea how to create the 405 error.
Is there a way to reproduce 405 error on my site?

HTTP response status code 405 means Method Not Allowed. This status code states that HTTP method was received and recognized by the server, but the server has rejected that particular method for the requested resource.
The easiest way to stimulate the response code 405 is to either
Try to access a non-existing resource/URL
Try to access an existing resource without the proper permission.
Try the following example with an HTTP tool like Postman
The following HTTP request tries to use PUT method on /api/values/ without the right permission
PUT /api/values/1 HTTP/1.1
Content-type: application/json
Host: localhost
Accept: */*
Content-Length: 12
"Some Value"
HTTP Response states code 405
HTTP/1.1 405 Method Not Allowed
Cache-Control: no-cache
Pragma: no-cache
Content-Type: application/json; charset=utf-8
Expires: -1
Server: Microsoft-IIS/8.0
X-Powered-By: ASP.NET
Date: Wed, 15 May 2013 02:38:57 GMT
Content-Length: 72
{"Message":"The requested resource does not support http method 'PUT'."}

problem with telnet HTTP/1.1 400 Bad Request

I was trying to do this:
Telnet into a Web server and send a multiline request message. Include in the request message the If-modified-since: header line to force a response message with the 304 Not Modified status code.
so I did steps below
telnet example.com 80
and then
GET /index.html HTTP/1.1
Host: example.com
and two enter.
and I got some information.
I added
If-modified-since: Thu, 17 Oct 2019 06:18:26 GMT
but still no 304 not modified.
this is what I get after GEt and Host
and
HTTP/1.0 501 Not Implemented
Content-Type: text/html
Content-Length: 357
Connection: close
Date: Fri, 30 Apr 2021 16:10:33 GMT
Server: ECSF (dcb/7F80)
HTTP/1.1 needs the Host header.
Your request should be:
GET /index.html HTTP/1.1
Host: hostname.tld
Edit
So if you are connecting to example.com:
GET /index.html HTTP/1.1
Host: example.com

What does Allow : GET mean in a HTTP response header?

What does Allow: GET mean below ?
HTTP/1.1 405 Method Not Allowed
Server: spray-can/1.3.1
Date: Fri, 21 Oct 2016 12:54:34 GMT
Allow: GET
Content-Type: text/plain; charset=UTF-8
Content-Length: 47
If you are using Spring Controller to process the request on the backend,
Make sure to use the annotation #RestController instead of #Controller

Cors Blocks Request with status 403 on Nginx

I am facing a strange issue with running CORS on Nginx, CORS is working fine for everything but one scenario when the Server responds with a 403 http response.
Basically when I login with correct credentials the cors request works fine , however when I provide wrong credentials for login the server(backend) responds with a 403 status and I get the following error
"NetworkError: 403 Forbidden - http://mydomain.com/v1/login"
login
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://mydomain.com/v1/login. This can be fixed by moving the resource to the same domain or enabling CORS.
If the credentials are correct I don't get this error and everything works perfectly.
I have done the configuration for enabling CORS and it seems to be working fine for everything else.
Following are the Request Headers

An option for nginx(>=1.75) is to specify always parameter in add_header :
If the always parameter is specified (1.7.5), the header field will be
added regardless of the response code.
I assume that you are using add_header directive to add CORS headers in the nginx configuration.
Nginx modules reference states about add_header:
Adds the specified field to a response header provided that the response code equals 200, 201, 204, 206, 301, 302, 303, 304, or 307.
To fix problem you could use ngx_headers_more module to set CORS headers also to error responses.
more_set_headers 'Access-Control-Allow-Origin: $http_origin';
more_set_headers 'Access-Control-Allow-Headers: Content-Type, Origin, Accept, Cookie';

Cross-domain chunked uploads using CORS

I have user-submitted files that I'm trying to upload in 10 MB chunks. I'm currently using raw XMLHttpRequest (and XDomainRequest) to push each individual slice (File.prototoype.slice) on the front end. The back end is Nginx using the upload module.
Just for reference, here's the synopsis of how I'm using slice:
element.files[0].slice(...)
I understand the cross-browser prefixed methods webkitSlice and mozSlice and all that.
The problem I have is with actually making the cross-domain request. I'm uploading from server.local to upload.server.local. In Firefox, the options request goes through fine and then the actual post fails. In Chrome and Opera, the options request fails with
OPTIONS https://URL Resource failed to load
Here are the headers from Firefox:
Request Headers
OPTIONS /path/to/asset HTTP/1.1

access-control-allow-credentials: true

The actual post request never leaves the browser. Nginx access logs never see the post. The browser halts it for some reason. How do I unravel why this post is being blocked?
Chromium 24
Firefox 18
Opera 12.14
I've verified all browsers support CORS properly here.
By pointing my uploads to https://cors-test.appspot.com/test, I have confirmed that the problem is definitely with the server-side headers.
The POST won't leave the browser if the preflight check does not return sufficient permissions and thus the POST request is not fully authorized. The request/response included in the question does look sufficient to me.
Are you sure you are setting withCredentials = true in your XMLHttpRequest?
Are you sure that you have valid (not self-signed) SSL certificates on your servers? The HTTPS might fail the CORS check even if you have added an exception for browsing the site with an invalid certificate.
Have you tried emptying your cache? You have Access-Control-Max-Age: 10000 set in your response headers. That's close to 3 hours. I know you've been working on this longer than that but while testing especially, set that header to zero instead so you don't go crazy with browser caching of old access permissions.
In general I'd start with going as permissive as possible with the CORS headers and slowly ratcheting up the the security to see where it fails. However, this is not completely straightforward. For example, according to the MDN documentation on CORS,
When responding to a credentialed request, server must specify a domain, and cannot use wild carding. The above example would fail if the header was wildcarded as: Access-Control-Allow-Origin: *
When I send the request part of your question to https://cors-test.appspot.com/test, I get back the following:
HTTP/1.1 200 OK
Cache-Control: no-cache
Access-Control-Allow-Origin: https://server.local:8443
Access-Control-Allow-Headers: content-disposition,content-type,x-content-range,x-session-id
Access-Control-Allow-Methods: POST
Access-Control-Max-Age: 0
Access-Control-Allow-Credentials: true
Cache-Control: no-cache
Expires: Fri, 01 Jan 1990 00:00:00 GMT
Content-Type: application/json
Content-Encoding: gzip
Content-Length: 35
Vary: Accept-Encoding

So you can start from there and add more and more security until it breaks to figure out what is the culprit.

Is there any httpresponse header that would redirect user to some page of my site?

I am a server. User sends http requests to me. I wonder if there is some http response header that would tall user web browser to auto rederect to some /my/server/page.html
You can use the Location header with a response code in the 3xx-range.
For an example:
HTTP/1.1 302 Found
Location: /my/server/page.html
301 and 302 HTTP codes can be used to redirect requests, like this:
HTTP/1.1 302 Object moved
Date: Fri, 28 Oct 2011 10:37:34 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
Location: http://www.xyz.com/abc
