Hi, I need to do an HTTP GET against an ASP.NET 4 service that returns
JSON.

Using cURL I get the expected JSON result, but if I use TFPHTTPClient
the server rejects the request with a code 202.

Here's the cURL request:

Code: [Select]curl -v "http://192.168.8.18:8285/efectores/1704/integra
ciones/api/v1/solicitud-
estudios?accessionNumber=21095&include=presentedForm"
*   Trying 192.168.8.18...
* Connected to 192.168.8.18 (192.168.8.18) port 8285 (#0)
> GET /efectores/1704/integraciones/api/v1/solicitud-
estudios?accessionNumber=21095&include=presentedForm HTTP/1.1
> Host: 192.168.8.18:8285
> User-Agent: curl/7.47.0
> Accept: */*

-- here's the JSON response--

Also I did a test using Python and it returned the expected result.

Code: Python  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i import
urllib2 # New lines begin herehttp_logger =
urllib2.HTTPHandler(debuglevel = 1)opener =
urllib2.build_opener(http_logger) # put your other handlers here
too!urllib2.install_opener(opener)# End of new lines request = urllib2
.Request('http://192.168.8.18:8285/efectores/1704/integraciones/api/v1
/solicitud-
estudios?accessionNumber=21095&include=presentedForm')response =
urllib2.urlopen(request)print "Response code was: %d" %
response.getcode()
But using TFPHttpClient version I'm getting a 202 error:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i lHttpClient
:= TFPHttpClient.Create(nil);                                        
                             lResponse := TStringList.Create;        
                                                                    
 try                                                                 
                                            lUrl := 'http://192.168.8.
18:8285/efectores/1704/integraciones/api/v1/solicitud-
estudios?accessionNumber=21095&include=presentedForm';       
lHttpClient.AddHeader('User-Agent', 'Mozilla/5.0 (compatible;
fpweb)');                                        
lHttpClient.Get(lUrl, lResponse);                                    
                                       finally                       
                                                                     
           lResponse.Free;                                           
                                                    lHttpClient.Free;
                                                                     
                    end;
The result is a status code 202.

I use TFPHTTPClient in many projects without issues, but if I point to
this specific server I get this wrong response, what can be
happening?.

Sorry, please ignore this, it's working perfectly without changes.
