mod jk - Apache not forwarding URLs containing semicolon to Tomcat (AH00128: File does not exist) -

-

we have apache 2.4 fronting tomcat via mod_jk.

when request "/abc/def/ghi/e380297.rhd" gets submitted mod_rewrite prepends web application context path "web" resulting in "/web/abc/def/ghi/e380297.rhd". afterwards request correctly passed thru tomcat.

but semicolon inserted in of path segments of url, e.g. "/abc/de;f/ghi/e380297.rhd", apache not pass request tomcat tries resource itself. not exist (ah00128: file not exist) return 404.

why apache behave , can rectify this?

edit:

i looked @ mod_jk log file , found: 

[debug] jk_map_to_storage::mod_jk.c (3798): no match /web/abc/de;f/ghi/e380297.rhd found

so looks if apache passing request thru mod_jk mod_jk not find mapping, strange me have mount defined:

jkmount /*.rhd ajp13

even more interesting when use following url

/abc/de.rhd;f/ghi/e380297.rhd

the request passed tomcat.

so mod_jk correctly regards semicolon start of path parameter (see http://doriantaylor.com/policy/http-url-path-parameter-syntax) next "/" not start next path segment mod_jk (not sure if correct or incorrect) never sees url ends in mounted extension ".rhd".
