Hi Yann Anyway, could you please try the attached patch and see if it works for you? >
I have applied your patch to my httpd-2.4.52 and created two test cases. One with a simple RewriteRule and a second one using a RewriteMap. Both are working fine. :-) Test logs attached: mod_rewrite_vs_proxy_pre_trans-v2_test_log.txt Thank you for the very quick response!
