Add retry for dynamic content #1166
Description
Hi,
getJson often get into an error that I believe is because HTTP server sometimes may return 404 or a wrong content, this is being parsed and the error is below:
ERROR: 2015/05/25 Cannot read json from resource http://127.0.0.1:3000/123test with error message invalid character 'E' looking for beginning of value
ERROR: 2015/05/25 Error while rendering page 123test.md: reflect: call of reflect.Value.Type on zero Value
Is there a retry policy for the dynamic content ?
Thanks
