> Current version of get_path_param doesn't expect ';' as path parameters separator so this urls are not correctly handled:
> /test.jsp;jsessionid=123123.NODE01;name=vale
> See for instance the mod_proxy_balancer implementation (in httpd 2.2.21):
> /* Retrieve the parameter with the given name
>  * Something like 'JSESSIONID=12345...N'
>  */
> static char *get_path_param(apr_pool_t *pool, char *url,
>                             const char *name, int scolon_sep)
> {
>     char *path = NULL;
>     char *pathdelims = "?&";
>     if (scolon_sep) {
>         pathdelims = ";?&";
>     }
>     for (path = strstr(url, name); path; path = strstr(path + 1, name)) {
>         path += strlen(name);
>         if (*path == '=') {
>             /*
>              * Session path was found, get it's value
>              */
>             ++path;
>             if (strlen(path)) {
>                 char *q;
>                 path = apr_strtok(apr_pstrdup(pool, path), pathdelims, &q);
>                 return path;
>             }
>         }
>     }
>     return NULL;
> }
> Severity of this bug to me is not so high since using more than one path parameters is not so common.
