I'm trying to modify the "Host" request header for a URL that is subject to proxying, but that doesn't seem to work. Setting ProxyPreserveHost On does work, but breaks other parts of the configuration. LoadModule rewrite_module modules/mod_rewrite.so LoadModule headers_module modules/mod_headers.so RewriteEngine On RequestHeader set Host www.somehost.com RewriteRule /cd4(.*) http://www.backend1:8080/cd4$1 [P] result between Apache en backend GET /cd4/survey.htm HTTP/1.1\r\n Host: www.backend.com:8080\r\n Is there something that I'm overlooking? (processing order of modules?) Kind Regards, Spil Oss --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
