Transform Manager Notification HTTP Post

Oct 27, 2011 08:43 PM|LINK

I'm trying to setup the transform manager notification service following the guide located here:
http://learn.iis.net/page.aspx/1031/sending-transform-manager-job-status-notifications-to-a-remote-web-application/

I have an asp.net website up and running with a page post.aspx in the root directory. For testing purposes I am writing the results to a local file.
If I run an http post tester with the message being posted shown below in the post message my results are written to the file with no issues.

However if Transform Manager tries to send the notification I receive the following error in windows event log:

The thread posting the notification message to http://localhost/post.aspx failed: The remote server returned an error: (500) Internal Server Error.. Message being posted :

<IISTransformManager><queue notificationTimeUtc="2011-10-27 20:16:01.5849">Failed</queue><workItem jobName="20111027201553_C40C184D5E8C4F368504489A9E8F8D22" folder="C:\SVN\Video\MyFailFolder" jobDefinitionId="f8e4fc67-5da1-4ac2-9c0b-3b6646b85a71" jobTemplateId="56025acd-badb-4a77-8b76-9d8839206092" jobSchedulerId="00000000-0000-0000-0000-000000000000" manifestName="20111027201553_C40C184D5E8C4F368504489A9E8F8D22.smil" instanceFileName="New Text Document.txt" queueTime="2011-10-27T20:16:01.5849696Z" progress="100" submitTime="2011-10-27T20:15:54.3875579Z" startTime="2011-10-27T20:15:54.4135594Z" endTime="2011-10-27T20:16:01.5759691Z" priority="3" status="Failed" taskCount="1" taskIndex="1" /></IISTransformManager>

Any ideas?...

Little more info on this after digging through more logs..

Exception message: A potentially dangerous Request.Form value was detected from the client (<IISTransformManager><queue notificationTimeUtc="...6">Running</queue><workItem jo...").

Trying to disable this I have added: <%@ Page validateRequest="false" %> and still no joy.

I'll try to give your code sample a try within the next week. But have you tried running the web application under Visual Studio and setting a BreakPoint in the Page_Load ? Also, you can try adding some logging logic in the code here and there to find out where it crashes.

The error 500 means internal error on the server... most likely the web application is throwing an exception of some sorts.

If the Web Application is not even loading, you might get a bit more details from IIS Failed Request Tracing

http://learn.iis.net/page.aspx/266/troubleshooting-failed-requests-using-tracing-in-iis/

partway in the page you'll find a "Enable Failed-Request Tracing" section that explains how to enable the FREB traces.

This will give you more details about the request comming in and why it threw a 500.

The application loads with no issue. Additionally the results expected (xml post written to text file) works with no issues when utilizing a standard HTTP post program such as:

http://teleflow.org/wiki/index.php5?title=HTTP_XML_Post_testing_tool
or
http://soft-net.net/SendHTTPTool.aspx (run this in xp compatability)

When using the http posting tools the breakpoints set on page load and throughout the method are hit. However the breakpoints do not get hit when messages are sent via Transform Manager. Possibly missing something in the web.config to disable potentially dangerous requests?
