From comments in #1600 (this was not addressed in the submitted patch, nor can I find a separate ticket for this issue):
In a conf file, you must handle _pathinfo before _scriptname because otherwise con->uri.path will be overwritten with whatever value you have set for _scriptname as can be seen here:
} else if (buffer_is_equal_string(rw->header, CONST_STR_LEN("_scriptname"))) {
int ret;
if ((ret = pcre_replace(rw->regex, rw->replace, con->uri.path, p->replace_buf)) < 0) {
switch (ret) {
case PCRE_ERROR_NOMATCH:
/* hmm, ok. no problem */
break;
default:
TRACE("oops, pcre_replace failed with: %d", ret);
break;
}
} else {
/* we matched, cool. */
buffer_copy_string_buffer(con->uri.path, p->replace_buf);
}
}
