[Spacewalk-list] Spacewalk server HTTPS Error 400 - Bad Request

[Radovan Drazny]

Robin,

this behavior is most likely caused by strict whitespace checking in httpd. 
Try adding "HttpProtocolOptions Unsafe" directive to httpd config on your SW 
server, and restart the httpd daemon. For more info see https://
httpd.apache.org/docs/2.4/mod/core.html#httpprotocoloptions

When an updated version of yum-rhn-plugin from Oracle will be available and 
installed on your clients, you can remove the directive from you httpd config.

Problem is, I'm not sure this config option is available in the httpd version 
shipped with Oracle linux. If httpd fails during the restart, remove the 
"HttpProtocolOption". 

In such case, the easiest workaround is what Avi recommended - you just have 
to obtain previous versions of httpd, httpd-tools and mod_ssl rpms, and do a 
manual downgrade.

Best regards

 Note that yum will try to contact the repo. when it runs most
