Shield specific *path* from rewriting in a rewritten domain?

Hi all,

I am experimenting with the PubMed stanza as it originates on
https://help.oclc.org/Library_Management/EZproxy/Database_stanzas/PubMed -
in particular I wanted to find a way to get PubMed's "Sign in to NCBI"
links to work through UMN's federated login so that users who follow those
individual sign in links while already proxied drop out of EZproxy and hit
the links directly.

I thought I might find a way to prevent a specific URL path from ever being
rewritten on an otherwise rewritten (proxied) domain but not finding any
such feature. Using Find/Replace with ^A does not seem to work in this
instance because the links are originally spelled out in the HTML like:

authid="university_of_minnesota" href="?authid=university_of_minnesota"

I can't use Replace with ^A here becuase it only works to follow http:// or
https://. AnonymousURL is not appropriate because we would not want it
rewritten at all, rather than rewritten but unauthenticated. I attempted to
stack two Find/Reaplce pairs first transforming the above into a full URL,
then rewriting it with ^A, but found that does not work either.

Is there a directive that would allow us to just prevent URLs with the
relevant path from being rewritten:
https://www.ncbi.nlm.nih.gov/account/partners ?

This is all only an experiment after we received a support question from a
user who attempted to do use the Sign in to NCBI links while already in the
proxy. I am first determining if it is possible to un-proxy this section of
the site before finding out what the actual repercussions of doing that
would be.

Thank you for any input,
--
