    a b Returns an absolute URL (i.e., a URL without the domain name) matching a given 
    891891view function and optional parameters. This is a way to output links without
    892892violating the DRY principle by having to hard-code URLs in your templates::
    893893
    894     {% url path.to.some_view arg1,arg2,name1=value1 %}
     894    {% url path.to.some_view arg1 arg2 name1=value1 %}
    895895
    896896The first argument is a path to a view function in the format
    897897``package.package.module.function``. Additional arguments are optional and
    If you'd like to retrieve a URL without displaying it, you can use a slightly 
    935935different call::
    936936
    937937
    938     {% url path.to.view arg, arg2 as the_url %}
     938    {% url path.to.view arg arg2 as the_url %}
    939939
    940940    <a href="{{ the_url }}">I'm linking to {{ the_url }}</a>
    941941
    This will follow the normal :ref:`namespaced URL resolution strategy 
    957957<topics-http-reversing-url-namespaces>`, including using any hints provided
    958958by the context as to the current application.

     961
     962For backwards compatibility, the ``{% url %}`` tag supports the old syntax
     963from previous Django versions of comma separating the arguments. The previous
     964syntax does not support commas as part of string literals in the arguments.
