add variable support to proxy_cache_valid directive

[Michael_Fillios]

Hello everyone

I want to use variables in proxy_cache_valid directive like the syntax
below
« set $var10 "10m";
     proxy_cache_valid 200 $var10; »

but I get the error « invalid time value »
so I tried to tweak a little in the ngx_http_file_cache.c file and I added
the following lines:

«    ngx_http_complex_value_t            cv;
    ngx_http_compile_complex_value_t    ccv;

    ngx_memzero(&ccv, sizeof(ngx_http_compile_complex_value_t));

    ccv.cf = cf;
    ccv.value = &value[n];
    ccv.complex_value = &cv;

    if (ngx_http_compile_complex_value(&ccv) != NGX_OK) {
            return NGX_CONF_ERROR;
    } »

the block after my code is 

«  valid = ngx_parse_time(&value[n], 1);
    if (valid == (time_t) NGX_ERROR) {
        ngx_conf_log_error(NGX_LOG_EMERG, cf, 0,
                           "invalid time value \"%V\"", &value[n]);
        return NGX_CONF_ERROR;
    }
»


also the output of Nginx -V is
