i want be able to find what is causing Apache to replace all non 2XX responses with its own error document. All i need to do is, comment or set off ProxyErrorOverride. With this Apache will proxy pass error response as is from backend server to UI without loosing content, example it sends error response of type Json as it is without loosing headers.but i don't know how to set this variable and where. any help pls?

I'm trying to do a rest call which has the query params like:
https://www.tutorialspoint.com/?hasName=true
I have to set hasName=true in Jmeter. I'm getting a 500 and I do have JSON data that I want to post at the same time. If I set the parameters using the parameter tab then I can't update JSON data in the body data. How can I do both things at same time? I tried adding user defined variables and it did not work.
You can set in HTTP Request the JSON in Body Data tab and put full URL in Path field
https://www.tutorialspoint.com/?hasName=true
As a special case, if the path starts with "http://" or "https://" then this is used as the full URL.
Do a successful request in the browser or any other tool and compare the request you're sending through jmeter. Check everything including request urls, cookies, headers etc. If you think its all exactly the same. Reach out to the server admins/app devs to check the web server/application logs to find out what is wrong either in server or your request.
The 500 Internal Server Error is a very general HTTP status code that
means something has gone wrong on the website's server, but the server
could not be more specific on what the exact problem is.
I'm new to Apache NiFi, and I developed an application to send JSON data to a NiFi endpoint via HTTP POST request.
In Apache NiFi, I have a HandleHTTPRequest processor connected to a PutFile processor then a HandleHTTPResponse processor. I've also tried using a LogAttribute processor. The response code and HTTP message from the NiFi web service is working properly, but I'm trying to make sure my JSON payload is being sent properly. Post is enabled in the HTTPRequest handler. Yet, the only files it's generating are blank and 0kb in size. Any ideas?
Based on the comments above the conclusion is that there was no problem on the side of Nifi.
It's definitely an issue with the Java code, I used postman again after changing some local firewall configurations and it successfully logs any POST requests that are sent to it and puts it in a file
The key step towards resolving the issue was trying to connect with something like Postman as #Binary Nerd and #Brian Bende suggested.
For one my client i am fixing one security issue where a hacker is changing request method from POST to GET. Can anyone tell me how I can detect such scenario on server side?
Server needs to serve both GET and POST requests but it needs to restrict those GETs which are originally POST and were converted to GETby hacker.
For an assignment, I have written a server that services HTML files and I am supposed to use my web browser as a test client. I am also told that if there is a request for a file that doesn't exist i should send the following
HTTP/1.1 404 Not Found\r\n\r\n and if anything else goes wrong
HTTP/1.1 500 Internal Server Error\r\n\r\n"
I have run tests that should cause those to be sent, but nothing occurs in my browser window? Should I be getting any visual feedback from sending such a request?
In an HTML response there should only be one CRLF (carriage return and line feed) after each line. So you can first remove the extra \r\n.
Also on the second line you can send an HTML response back to the client saying what the error was if you want to show an error. This is normally what a typical web server does where it has its default error page if one is not defined. If you are not sending any HTTP headers, then you can insert the HTML body you want to send back such as <h1> No page found</h1> as the second line.
To include an "entity" in an http response
HTTP/1.1 404 Not Found
Content-Type: text/html
Content-Length: 10
01234576789
each line is ended by CRLF. Be sure to count the Content-Length correctly.
I see that this is a learning exercise, and understand that you may have been told to implement the server this way. But bearing that in mind ...
This is the wrong way to implement a web server / service. The right way is to find an existing implementation and build your service on top of that.
You could use a Java EE web container; i.e. something that implements the Servlets spec.
You could use a non-servlet framework (like Grizzly).
You could build on top of a server-side HTTP protocol stack; e.g. using Apache the HttpComponent library.
Building a web server from the ground up is a lot of work if you are going to do it properly. And the chances that you won't do it properly; i.e. you won't implement your service according how the HTTP spec says a server should behave. You will leave things out, do things the wrong way, etc.
Please don't do it. There are already too many broken (i.e. non-compliant) web servers out there. We don't need more.
And if you DO decide to implement HTTP from the ground up, then you (YOU) need to thoroughly read and understand the HTTP spec. And you (YOU) need to do your own basic research on how browsers implement the client side of the spec ... and what you therefore need to do on the server side to make browsers behave "normally".
I am developing an application to send a text message/sms to a user base and receive their responses. I have been given a wsdl which I have used to consume the service to sendsms using netbeans IDE .So far so good.
Now the problem is when I receive a text message a soap request is posted over to a location on our server. The request-response is as follows:
<a>http://www.csoft.co.uk/sms/api/sms_to_soap.htm</a>
I have checked the provider's sample API section but they do not have any material that does something similar.
My question is how do I parse the soap request and send the corresponding response? Also I have to check the messages and filter them for offensive/obscene content. I have the wsdl, xsd, java classes generated by netbeans, but I cant get around how to use them to achieve the goal. Any help or a pointer in the right direction would be greatly appreciated.
Thanks
