Can squid modify header by adding httponly flag to cookie ?

[Jeannette Brown <jeannette.k.brown@xxxxxxxxx>]

I would like to see if squid can modify headers on outbound web pages
to add the httpOnly flag to specific session cookies.

Old web app server does not know how to add httpOnly flag to session cookie.

Squid 2.7 is used in front of web app server in reverse proxy mode.
