I'm using apache with mod_proxy to make the server appear at a different location and port and need to tweak some absolute references in the content as it goes by. mod_proxy_html looked promising - and appears to work - but seems to be making the httpd process consume a lot of CPU on occasion. mod_substitute as included in more recent apache versions should work and mod_sed is another possibility. Has anyone solved this problem with the version of httpd in RHEL/Centos? -- Les Mikesell lesmikesell at gmail.com
