Posted: Wed Nov 23, 2011 6:01 am Post subject: [SOLVED] Error due to double header in SOAP/XML monitor |
|
|
Hi Alex,
I have the following problem with Hostmonitor version 9.02 Beta on Windows XP SP3.
After creating a SOAP/XML monitor and using Fiddler (HTTP Debugging Proxy) I found out that Hostmonitor sends two headers
and returns an HTTP/1.1 Internal Server Error.
Content-Type: text/xml; charset=utf-8
Content-Type: application/x-www-form-urlencoded
The monitor is a POST request with SOAP version 1.1 and I created a header for the SOAPAction.
Could you take a look and see if you can reproduce this problem ?
Best regards,
Jeroen
FYI : The test method is called SAOP/XML instead of SOAP/XML.

HostMonitor inserts "Content-Type: text/xml; charset=utf-8" into HTTP header when you are using POST method and SOAP version 1.1
HostMonitor does not insert "Content-Type: application/x-www-form-urlencoded" into header.
We just rechcked code and performed some tests, it works properly.
BTW: What version of Internet Explorer is installed on your system?

Ok, thanks for checking. Do you have any ideas where the second header is coming from ?
I have installed IE8 (and FF 3.6.22) on my system.
I also tested the same monitor (also in application mode but without proxy) on a system with Windows Server 2003 SP2 with IE7 and it returns the same error.
Below the message that is returned when I use the "Test" button.
HTTP/1.1 500 Internal Server Error
Content-Type: text/xml
X-Backside-Transport: FAIL FAIL
Connection: close
Set-Cookie: sticky-key=3460502955.20736.0000; expires=Thu, 24-Nov-2011 15:29:30 GMT; path=/
Vary: Accept-Encoding
What is causing the FAIL FAIL message ?
BTW: A great idea to implement this type of test. At the moment we use Shell Script tests with a powershell script to check the status of our SOAP services but this puts a heavy burding on CPU & Memory resources.
Regards,
Jeroen |

Is your server accessible from internet?
Could you export test settings into text file and send it to us?

No, server isn't accessible from internet.
I will mail you the test settings.

We tested HostMonitor with IE8 as well, works fine.
Can you setup HostMonitor to perform URL requests without using proxy? Select "direct to net" option on "Connection/Access method" page in the Options dialog.

I think its good idea to ask your web server administrator about this problem. He knows what exactly web server is used, what script processes this SOAP request, what parameters are required by this script, he can check web server log files and so on...
May be your server supports SOAP version 1.2 as well?

Standard setting is "direct to net", I only use a proxy for debugging purposes.
We don't support SOAP 1.2 at the moment.
The check works fine if I change the check to a GET (WSDL) instead of a POST.
Could you please have another look at this problem ?
We want to upgrade from HM 8.28 but only if we can use the SOAP checks. |

We re-tested HostMonitor version 9.02 and 9.16 (not available for download yet) with IE 8.0, everything looks fine, only one "Content-Type:" listed in HTTP request.

May be your server accepts only GET requests?
If GET request works fine, why do you want to use POST request?

I check my (HTTP) request headers with the free web debugger proxy Fiddler (http://www.fiddler2.com). How do you check yours ?

No, the server accepts both request and this problem occurs with different servers/applications.
Quote: |

Only to test if a valid connection can be made to the server/application. We need to use POST requests.
Below is the check I tried yesterday, the (raw) request/response are from Fiddler. I changed the domain name in both request and response.
Request:
POST https://www.xxxxx.com/em/lse/sysint/sysint.asmx HTTP/1.1
SOAPAction: http://www.teledyne.com/lse/SysInt/IsServiceAlive
Content-Type: text/xml; charset=utf-8
Content-Type: application/x-www-form-urlencoded
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0)
Host: www.xxxxx.com
Content-Length: 232
Connection: Keep-Alive
Cache-Control: no-cache
Pragma: no-cache
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:sys="https://www.xxxxx.com/em/lse/SysInt"><soap:Header/><soap:Body><sys:IsServiceAlive xmlns="https://www.xxxxx.com/em/lse/SysInt"/></soap:Body></soap:Envelope>
Response:

<h1>Bad Request (Invalid Header Name)</h1>
Because of the double request header, do you agree with me that the problem must be on the sending end (my workstation) and not on the receiving end (server/application/firewall/etc) ?

We used Wireshark Network Protocol Analyzer (www.wireshark.org), also, we checked traffic, using Fiddler.
Both analyzers show that HostMonitor sends only one Content-Type header.

Do you use Fiddler installed on local system, where HostMonitor runs ?
Problem should be between HostMonitor and Fiddler.
Question is what 3-rd party application modifies HTTP headers, sent by HostMonitor. |

Also, could you export test settings into text file and send to us + hostmon.ini file (support@ks-soft.net)?

Fiddler and Hostmonitor (9.16) are both installed on my workstation. Today I also installed Hostmonitor (9.16) on a server (windows server 2003 SP2 with IE7) and used the same test and got the same response (HTTP/1.1 400 Bad Request).

Not necessarily, how do you explain that I get the same response if Fiddler isn't used (direct connection) or installed (server).

I'm not yet convinced that it is the 3rd party application.

I have been able to solve this problem with a fix provided by the support team.
The problem was related to the HTTPS protocol.
The fix will be included in the next release of Hostmonitor.
My compliments !!!

Sorry for delay
If we knew its related to HTTPS protocol we could fix it much sooner but we spent most of time checking HTTP module...
