Apache mod_rewrite fake pushState directory mapping - apache

If have played around a lot with mod_rewrite rules in my httpd.conf file. Regardless of my research i haven't been able to get a couple of things working.
This is my file structure:
/
-index.php
-app.php
/css
-style.css
/js
-script.js
The server should either serve the index.php (home page) or app.php (single application page). Both the script and style files are included in both php files.
Goals
My domain domain.com should serve the index.php, the address bar should show www.domain.com
(This seems to work already, per default.)
The subdomain domain.com/a should be changed to domain.com/a/ if necessary. This domain should serve the app.php file.
(This is already working to an extend. One problem is that the relative links inside app.php are wrong, because the file "thinks" it is in a subdirectory instead of root. This I would like to change)
Anything after domain.com/a/ e.g. domain.com/a/user/10 should stay in the address bar and serve the app.php as usual. Ideally, to preserve relative links again, the file should "know" it is in the root folder.
(This is in order to support a "fake" pushState server) EDIT Clarification: Everything after the /a/ will be interpreted by my Javascript app. When the client clicks a link like domain.com/a/user/10 there will be no extra request to the server.
Bonus
Add trailing slashes to all URLs except the root url.
e.g. turn domain.com/a/user/10 into domain.com/a/user/10/
Add www to URL in case it is missing.
What I've tried
-add www
RewriteCond %{HTTP_HOST} !^$
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301]
-add slashes
RewriteCond %{REQUEST_URI} !(/$|\.)
RewriteRule (.*) %{REQUEST_URI}/ [R=301]
-redirect /a/
RewriteCond %{REQUEST_URI} ^(/a/)$
RewriteRule ^ /app.php
Any pointers or help are greatly appreciated! Thanks.
Edit
I have used this tool http://htaccess.madewithlove.be/ to test some conditions.

.htaccess rewrite all contents from subdomain to domain

I rewrited a subdomain to a section on my site:
https://music.example.com points to https://example.com/section.php?url=music
RewriteCond %{HTTP_HOST} ^music.example.com
RewriteRule ^(.*)$ section.php?url=music/$1 [L,NC,QSA]
But I need to use the same images, css, etc. for this (and other) subdomains.
https://example.com/images/img.jpg
Should be accessible from https://music.example.com/images/img.jpg
I tried to find a solution but I might not be doing the right search.
RewriteCond %{HTTP_HOST} ^music.example.com
RewriteRule ^(.*)$ section.php?url=music/$1 [L,NC,QSA]
This rule internally rewrites (not "redirects") a request of the form music.example.com/<anything> to section.php?url=music/<anything>. ie. Everything, including all images and CSS etc. This is much more than stated in your description, in which you only want the root directory to "point to" https://example.com/section.php?url=music.
If you only want the root directory to be rewritten then restrict the regex ^(.*)$ to only match the root.
For example:
RewriteCond %{HTTP_HOST} ^music\.example\.com
RewriteRule ^$ section.php?url=music [QSA,L]
NB: Don't forget to backslash-escape the literal dots in the regex.
This now naturally excludes everything else from being rewritten, except for requests to the subdomain's root directory, ie. https://music.example.com/ only.
.htaccess redirect all contents from subdomain to domain
As noted above, this is an internal "rewrite", not an external "redirect". And neither does this rewrite from subdomain to domain. The requested hostname does not change and it is assumed that both the subdomain and domain apex point to the same place on the filesystem.

Apache mod_rewrite from a folder to a different domain doesn't work with trailing slash

I'm trying to rewrite URLs from old.domain.tld/project to domain.tld/subfolder/project using .htaccess in the project directory on the old server. I think I need to check for the host name so the rule only applies to the old server, even if the .htaccess file is also put on the new server.
I've tried the following .htaccess file:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^old\.domain\.tld$ [NC]
RewriteRule ^(.*)$ https://domain.tld/subfolder/project/$1 [R=301,L]
This works fine for URLs like https://old.domain.tld/project/index.php?p=q (redirects to https://domain.tld/subfolder/project/index.php?p=q) but not for the URL without the trailing slash—https://old.domain.tld/project ends up being redirected to https://domain.tld. Very odd! How do I make this work for both types of URL?
I tried a rather different method to make this a generic redirect, that could be included even if the folder name wasn't project, but this has the same problem:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^old\.domain\.tld$ [NC]
RewriteCond %{REQUEST_URI} ^(.*)$
RewriteRule . https://domain.tld/subfolder/%1 [R=301,L]
In a server-wide configuration, a slash is appended to all requests for index files, e.g. old.domain.tld/project is redirected to old.domain.tld/project/. Could this be causing a problem?

301 redirect not working properly (my guess is b/c I'm dealing with Add-on domains)

I have a primary/account domain (PrimaryDomain.com) and a couple add-on domains (AddOnDomain1.com and AddOnDomain2.com) I've recently switched the content from AddOnDomain1.com to AddOnDomain2.com and I want everything to redirect to the exact same location (folders, files, images, etc.)
Here's what I have in .htaccess of my public_html folder (for PrimaryDomain.com):
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.AddOnDomain1\.com$
RewriteRule (.*) http://AddOnDomain2.com/$1 [R=301,L]
RewriteCond %{HTTP_HOST} !^AddOnDomain1\.com$
RewriteRule (.*) http://AddOnDomain2.com/$1 [R=301,L]
It trys to redirect but here's what happens (with an image as an example). When I enter:
http://AddOnDomain1.com/img/logo.png
It redirects to:
http://AddOnDomain2.com/AddOnDomain1/img/logo.png
Notice how it adds that folder (in bold)?...which of course is the add-on domain directory name. Anyone aware of a fix for this scenario?

htaccess adding WWW and changing filename in subdirectory

I know similar questions have come up, though often without a working answer. I'm hoping to have better luck!
I have an .htaccess file in my root directory adding "www" to everything:
RewriteEngine on
RewriteCond %{SERVER_NAME} ^mysite.org
RewriteRule ^(.*)$ http://www.mysite.org/$1 [R=permanent,L]
This generally works fine. I have a subfolder (/myquiz/) in which the old index.html file has been replaced with index.php. I know there are external links to /myquiz/index.html, so I want to make sure those redirect. Leaving index.html in place and trying to redirect from that led to some odd behavior, but adding an .htaccess in that directory works for that:
RewriteEngine On
RewriteBase /
RewriteRule ^index\.html?$ /myquiz/index\.php [NC,R]
Trying to load index.html redirects to index.php as hoped for, and the WWW gets added if needed. But requesting mysite.org/myquiz/index.php directly does not add the WWW.
I tried adding "RewriteEngine inherit", but that resulted in calls getting redirected to my root folder instead. A great trick if I want to make a subfolder inaccessible, but not helping here. I also tried just adding the code from my root .htaccess into the beginning of my subfolder's .htaccess, but that worked no better.
Any ideas?
You shouldn't need to add another htaccess file in the myquiz folder. This should work in the htaccess file in the root of the site. Remove the htaccess file in myquiz and try this.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^mysite\.org
RewriteRule ^(.*)$ http://www.mysite.org/$1 [R=301,L]
RewriteRule ^myquiz/index\.html$ /myquiz/index.php [R=301,L]
Also I wouldn't use %{SERVER_NAME} unless your are sure the name is set properly in the config file. Then it can be more reliable than HTTP_HOST, otherwise I would instead use %{HTTP_HOST}.
I think inherit would work if you add an L flag to the rule that you have in your myquiz folder:
RewriteRule ^index\.html?$ /myquiz/index\.php [NC,R,L]
So that it redirects first, then the inherited rule (the www) gets applied after.
You could also just put both rules in the same file:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^mysite.org$ [NC]
RewriteRule ^(.*)$ http://www.mysite.org/$1 [R=permanent,L]
RewriteRule ^myquiz/index\.html$ http://www.mysite.org/myquiz/index.php [R=permanent,L]

mod_autoindex does not respect mod_rewrite rules

I have a directory structure similar to:
public_html/
example.com/
index.php
subdir/
file.jpg
I'm using shared hosting, so http://example.com maps to /public_html/ for its root, and I can't change this. I've added a mod_rewrite rule to handle this issue:
RewriteEngine On
RewriteRule ^$ example\.com/ [L]
RewriteRule (.*) example\.com/$1/ [L]
If I browse to http://example.com/subdir (without the trailing /) it will list file.jpg , but the URL for it will be http://example.com/file.jpg. The parent directory link is http://example.com/example.com/.
If I browse to http://example.com/subdir/ (with the trailing /) it will list file.jpg with the proper URL: http://example.com/subdir/file.jpg. However, the parent directory link is http://example.com/example.com/subdir/.
I'm very confused for what's going on and I'd love any help on this.
(Note that if I take off the final / in the mod_rewrite rule then going to http://example.com/subdir without the / will redirect to the http://example.com/example.com/subdir/ variant. Also, the parent directory for the listing at http://example.com/subdir/ changes to http://example.com/example.com/, which is almost correct.)
This could be caused by a disabled DirectorySlash. So try to enable it or use this rule to do the same with mod_rewrite:
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule .*[^/]$ %{REQUEST_URI}/ [L,R=301]
