Summary0015774: CTest result submission over http fails to set Content-Type header which runs afoul of ModSecurity rules
DescriptionOn some web hosting providers, ModSecurity rules are in place that prevent using CTest with a CDash installation on that provider. The particular rule looks like this (pieces removed for anonymity):

ModSecurity: Access denied with code 406 (phase 2). Match of "rx ^0$" against "REQUEST_HEADERS:Content-Length" required. [msg "Request Containing Content, but Missing Content-Type header"] [uri "/CDash/submit.php"]

CTest runs show this error:

Submit files (using http)
   Using HTTP submit method
   Drop site:http://<mysite>/CDash/submit.php?project=<myproject> [^]
   Error when uploading file: <mypath>/Testing/20151005-0900/Build.xml
   Error message was: The requested URL returned error: 406 Not Acceptable
   Problems when submitting via HTTP

The same 406 error is seen using curl -T:

# curl -T <mypath>/Testing/20151007-0900/Build.xml http://<mysite>/CDash/submit.php?project=<myproject> [^]
<head><title>Not Acceptable!</title></head><body><h1>Not Acceptable!</h1>

An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security.


These hosting providers do not allow any method of disabling particular rules or ModSecurity in general.

While we can debate the merits of this rule, it is simple to work around by providing a Content-Type header. E.g., curl -d works:

# curl -d @<mypath>/Testing/20151007-0900/Build.xml http://<mysite>/CDash/submit.php?project=<myproject> [^]
<cdash version="2.2.2">
