I have an old web application (not maintained anymore) of which a small part is still needed; this is displayed in iframes.Unfortunately, the old application uses ISO-8859-1 encoding (which it doesn't declare; it simply sends Content-Type: text/html), while the new one (of course) uses UTF-8.  Thus, since the encoding of the iframe contents is not specified, UTF-8 is expected, and thus several characters look wrong.The VirtualHost of the old application does some rewriting to a JBoss application:RewriteRule ^/(.*) http://localhost:9080/$1 [L,P]I'm able to edit this VirtualHost (while nobody will touch the application itself anymore); how would I add the encoding information?E.g., for all contents with a textual content type which lack encoding information (naked Content-Type: text/html), append ; charset: ISO-8859-1.Any simple code snippet?  Thank you!
Append encoding information to HTTP response headers
apache;content encoding
