Apache server is forwarding application requests to Crowd. However the requests fail with the following error:

ERROR [xfire.transport.http.HttpChannel] Server returned error code = 417 for URI : https://your_domain/crowd/services/SecurityServer. Check server logs for details


The Apache server does not support the HTTP header Expect, which was added by the client application to the requests.


Use mod_header to remove the Expect header from the requests:

1. Edit your Apache configuration file (usually the httpd.conf file) by adding the following line:

LoadModule headers_module modules/mod_headers.so

2. Add the following lines to the same configuration file:

<IfModule mod_headers.c>
RequestHeader unset Expect early
