There was a post recently that was having problems with Varbase and multiple redirects.

https://www.hiawatha-webserver.org/forum/topic/2626

The problem is rooted in the Redirects module (included in the Varbase distribution) and the fact that Drupal 8 handles rewrites differently (more like WordPress). I have changed my configuration to the following and it seems to be working fine.

Old:

UrlToolkit {
    ....
    Match /(.*)\?(.*) Rewrite /index.php?q=$1&$2
    Match /(.*) Rewrite /index.php?q=$1
}

New:

UrlToolkit {
    ...
    Match ^/(.*)\?(.*) Rewrite /index.php?$2
    Match ^/(.*) Rewrite /index.php
}

There are more configurations that should change in the UrlToolkit for Drupal8. I will post soon with a more complete configuration that matches the root .htaccess file settings and incorporates .htaccess settings from other directories (like the private file path).

Your UrlToolkit rule could probably be reduced to this:

UrlToolkit {
    ...
    Match [^?]*(\?.*)? Rewrite /index.php$1
}

Its black magic to me but it works! Thanks Hugo.

[^?] means every character, except the question mark.
* means the pattern before that, 0 or more times
So, [^?]? means a string of length 0 or more, not containing a question mark.

\? means the question mark itself.
. means any character.
\?.* means a question mark, followed by 0 or more characters.
The ? at the end means that the pattern before it is optional.

So [^?]*(\?.*)? means a string not containing a question mark, optionally followed by another string starting with a question mark.
