In v1.2.19, in the apache-1.3 mod_jk.c code, the jk_add_env_var function used to do: conf->envvars_in_use = JK_TRUE; The apache-2.0 code still does this in 1.2.21 but the apache-1.3 code no longer does which causes JkEnvVar to not work at all. I can't get ahold of 1.2.19 source or I would submit a patch for this.
I forgot to mention. We added that code snippet back into our local source and recompiled it, tested it, and it worked.
Fixed in the SVN. Will be part of 1.2.22 Thanks for spotting that.
Move a couple of fixed JK issues from resolved to closed.
