[Zope] - Apache's DSO and mod_rewrite.

Just simple question. Should I compile in mod_rewrite statically? On RedHat 5.2, I have httpd(apache) which configured to load dynamically rewrite_module. It fails to deliver authent header to Zope, always, even with the directives in WEBSERVER.txt in Zap doc directory. With "RewriteLog 9" directive, apache says it 'pass'es to Zope. It just seems OK for this unitniated httpd user. Yes, Zap works fine. BUT I do not want to use it. My(rather our) site goes through frequent "httpd restart", and having two (diffently configured )httpd's causes problem. So, I want the source of rewrite problem. Did I do something wrong or mod_rewrite must be compiled in staticall? Thanks, Kwan Soo.
