I have asked this question on stack overflow as well. I have an apache server and a fastcgi script. When I try to send POST request to my script, it fails giving me the 413 error. If I send in no parameters, my script actually runs giving me error in json (as expected).



I am using curl to send data to my script:



curl --data -v 'name=test&address=abc&phoneNumber=0987654321&password=test123' http://localhost/cgi-bin/add-user.fcg


It gives this output:

I am sending 61 bytes! I feel that is too low for this error. This is what I have done till now:




  1. I did not have LimitRequestBody in my httpd.conf, so it should have been defaulted to 0 (aka unlimited). But still, I added LimitRequestBody 1024000 and restarted the server

  2. Then I read somewhere that mod_security might have interfered. So I added <IfModule secruity2_module>
    SecRequestBody Off
    </IfModule>
     but to no avail

      I have asked this question on stack overflow as well. I have an apache server and a fastcgi script. When I try to send POST request to my script, it fails giving me the 413 error. If I send in no parameters, my script actually runs giving me error in json (as expected).



      I am using curl to send data to my script:



      curl --data -v 'name=test&address=abc&phoneNumber=0987654321&password=test123' http://localhost/cgi-bin/add-user.fcg


      It gives this output:

      I am sending 61 bytes! I feel that is too low for this error. This is what I have done till now:




      1. I did not have LimitRequestBody in my httpd.conf, so it should have been defaulted to 0 (aka unlimited). But still, I added LimitRequestBody 1024000 and restarted the server

      2. Then I read somewhere that mod_security might have interfered. So I added <IfModule secruity2_module>
        SecRequestBody Off
        </IfModule>
         but to no avail


      This is my httpd.conf:

      I have asked this question on stack overflow as well. I have an apache server and a fastcgi script. When I try to send POST request to my script, it fails giving me the 413 error. If I send in no parameters, my script actually runs giving me error in json (as expected).



      I am using curl to send data to my script:



      curl --data -v 'name=test&address=abc&phoneNumber=0987654321&password=test123' http://localhost/cgi-bin/add-user.fcg


      It gives this output:

      I am sending 61 bytes! I feel that is too low for this error. This is what I have done till now:




      1. I did not have LimitRequestBody in my httpd.conf, so it should have been defaulted to 0 (aka unlimited). But still, I added LimitRequestBody 1024000 and restarted the server

      2. Then I read somewhere that mod_security might have interfered. So I added <IfModule secruity2_module>
        SecRequestBody Off
        </IfModule>
         but to no avail


      This is my httpd.conf:
