h1. Conditional Request Headers {{>toc}} *Module: mod_setenv* h2. Description The setenv module allows influencing the environment external applications are spawned in and the response headers the server sends to the clients. h2. Automatic Decompression If you have a lot text-files compressed with gzip on disk and want that the browser is decompressing them on retrival you can use setenv to inject the Content-Encoding header: <pre> $HTTP["url"] =~ "(README|ChangeLog|\.txt)\.gz$" { setenv.add-response-header = ( "Content-Encoding" => "gzip") mimetype.assign = ("" => "text/plain" ) } </pre> h2. Options *setenv.add-environment* Adds a value to the process environment (aka environment variables) that is passed to the external applications: <pre> setenv.add-environment = ( "TRAC_ENV" => "lighttpd", "RAILS_ENV" => "production" ) </pre> *setenv.add-response-header* Adds a header to the HTTP response sent to the client: <pre> setenv.add-response-header = ( "Content-Encoding" => "gzip" ) </pre> *setenv.add-request-header* Adds a header to the HTTP request that was received from the client: client :: <pre> setenv.add-request-header = ( "X-Proxy" => server.name ) </pre> *setenv.set-request-header* *setenv.set-response-header* *setenv.set-environment* These directives _set_ the given values, rather than appending the given values to the headers or environment. These directives take precedence over the setenv.add-* counterparts. Set a blank value for request or response header to remove the header.
