Need help about reqrep (urgent)
Hey there, I have trouble with direct “reqrep” what I want is : My main web site is : caipiao.aaa.com My second web site is: www.bbb.com My goal is redirect URL from caipiao.aaa.com/ kaijiang ->www.bbb.com/result_aaa , but the URL in the browse still need to display caipiao.aaa.com/kaijiang what I did is: Frontend: acl acl_dom_caipiao.aaa.com hdr_dom(host) caipiao.aaa.com acl acl_url_kaijiang path_beg -i /kaijiang use_backend cs_aaa_caipiaos_1 if acl_dom_caipiao.aaa.com acl_url_kaijiang backend: backend cs_aaa_caipiaos_1 reqrep ^([^\ ]*)\ /kaijiang(/.*) \1\ /result_aaa\2 option httpchk GET / HTTP/1.1\r\nHost:\ www.bbb.com server srv_aaa_caipiaos_1_01 www.bbb.com:80 check when I access caipiao.aaa.com/kaijiang, I get a 404 error, looks like reqrep did not working~ but if make a little change as below: acl acl_url_result path_beg -i/result_aaa use_backend cs_aaa_caipiaos_1 if acl_dom_caipiao.aaa.com acl_url_result then I can access caipiao.aaa.com/result_aaa directly, So there should be a problem on reqrep Could you help to analyze the root cause of this ?
