Reference rewriterule matched group in a rewritecond regex?

I am using Apache's mod_rewrite module. Is there a way to reference a group captured by RewriteRule within the regex of RewriteCond?

For example:

RewriteCond %{REQUEST_URI} ^(.*(?=/#How can I 'paste' $1 = RewriteRule's (.*) group here?#$))
RewriteRule ^(.*)$ - [E=BASE_PATH:%1]

Here I will match the base path of the request URI, for example, if I request mysite.domain/subdir/my/site/dir, and .htaccess is inside subdir/ then:

1) RewriteRule ^(.*)$ ----> ^(my/site/dir)$ -----> $1 = my/site/dir
2) RewriteCond /subdir/my/site/dir ^(.*(?=/#I need to 'paste' the $1 RewriteRule's matched group here#$))

How can I do that so that my RewriteCond regex is generated 'dynamically' and becomes:

^(.*(?=/my/site/dir$))

Where my/site/dir is what was matched in RewriteRule's $1 group?

Not sure I understand your question, but here is a way to get the RewriteBase dyanmically

RewriteEngine on

RewriteCond $1-%{REQUEST_URI} ([^-]*)-(.*?)\1$
RewriteRule ^(.*)$ - [E=BASE:%2]

Your RewriteBase path is now available for use in the env %{ENV:BASE}
