Regression Works in ubuntu: "apache2/jammy 2.4.52-1ubuntu4 amd64" (and earlier) Fails in "apache2/jammy,now 2.4.55-1+ubuntu22.04.1+deb.sury.org+2 amd64 [installed]" Have 2 virtual servers with flat html pages that use SSI with multi-level virtual="file.html" includes (e.g. page.html includes "top-of-page.html" which includes "brand_menu.html") To differential between the 2 virtual servers, I use a .htaccess redirect for server #2 RewriteEngine On RewriteRule "ssi/top/brand_menu.html" "/ssi_maps/brand_menu.html" This causes the output to be line noise. Pages that don't use the SSI redirect are fine. Commenting out the "RewriteRule" is fine (just outputs the first server's "brand_menu.html") This is the line that's causing the problem <!--#include virtual="top/brand_menu.html"--> If mod_redirect gets involved in that line, the output is a page of line noise Work around <!--#if expr="%{HTTP_HOST} == 'maps.walkingclub.org.uk'" --> <!--#include virtual="/ssi_maps/brand_menu.html"--> <!--#else --> <!--#include virtual="top/brand_menu.html"--> <!--#endif --> Bit scary at first. Upgrading Apache2 has never caused a problem before. Thank you for the **amazing** work for the whole internet you are doing.
ubuntu curl --compressed (which doesn't use brotli compression, just gzip) DOES get the correct page, which is strange a "test your url around the world" website shows line-noise each time I'm wandering if its mod-includes + mod-rewrite + mod-brotli all together that's getting it wrong - it is some difference between curl fetching a page, and chrome fetching it.
