Since you store the username in the cookie you are probably not concerned about
security. In this case it might be sufficient to append the username by
rewriting the query string:
RewriteRule ^/my/map /my/map?user=%{REMOTE_USER} [QSA,PT]
The loadParams() in cgiutil.c only works on the QUERY_STRING and COOKIE. If you
like you can insert at line 267:
if ((s = getenv2("REMOTE_USER", thread_context)) != NULL) {
if(m >= maxParams) {
maxParams *= 2;
request->ParamNames = (char **)
msSmallRealloc(request->ParamNames,sizeof(char *) * maxParams);
request->ParamValues = (char **)
msSmallRealloc(request->ParamValues,sizeof(char *) * maxParams);
}
request->ParamNames[m] = msStrdup("remote_user");
request->ParamValues[m] = msStrdup(s);
m++;
}
I haven't tested this but since it's pretty straight forward it should work.
But that's not very generic. Probably the MAP.WEB.METADATA could be used to
define a "import_env_vars"-key with a list of names to be imported from the
environment...
