Apache2, mod_rewrite - use variable from prev condition in next condition

Question

I would like to check if file exist in subdirectory. And I mean subdirectory that "is taken" from "subdomain".

Eg. url: "test.domain.com/file.txt" file location is "/test/file.txt"

I have wildacrd and i can't hardcode "test" directory. How can i do it?

I tried add %{DOCUMENT_ROOT}%1/$1 but this dosen't work.

Fixes in OP's attempts: You need not to use condition RewriteCond %{ENV:REDIRECT_STATUS} ^$ in 2nd Rules sets, even first one may not need it but for safer side you can have it. Then your sequence of accessing path from %{DOCUMENT_ROOT} was not correct which was corrected here.
