Hi, i just setup a Nextcloud instance in conjunction with OnlyOffice. NC makes heavy use of mod_rewrite and i try to understand it. mod_rewrite isn't easy, so i have some questions and hope for help: 1. Is a RewriteCond just valid for the consequent rule or for all consequent rules ? 2. Example: "RewriteRule ^core/js/oc.js$ index.php [PT,E=PATH_INFO:$1]" Are Backreferences also in flags possible ? What is the content of $1 ? I thought backreferences belong to parts of the pattern which are in parentheses ? There are no parentheses. 3. Example: RewriteCond %{REQUEST_FILENAME} !\.(css|js|svg|gif|png|html|ttf|woff2?|ico|jpg|jpeg|map|webm|mp4|mp3|ogg|wav)$ The ! (exclamation mark) stands for a negotiation. Does that mean this condition is only fullfilled if the file does NOT have an extension like .css, .js ... ? 4. Example: RewriteRule .* - [env=HTTP_AUTHORIZATION:%{HTTP:Authorization}] What does this rule do ? All requests (.*) aren't substituted (-). But ... an environment variable HTTP_AUTHORIZATION is set to ... ? What means %{HTTP:Authorization} ? Is that also a kind of a backreference ? More questions will follow :-)) Thanks.
