python - How to make a page not directly accessible in Flask? -

-

I am developing a web application using flask microfworks.

I have to see a scene, it is only accessible when it is not sent directly from any other view and to users.

To make it more clear: 

  @ app.route ('/', methods @ ('GET', 'POST')) @ app Route ('/ home', methods = ('GET', 'POST')) DEF Home (): # Some code return redirects (url_for (in 'progress', parameter) @ app.route (' / path / & lt ; Parameters & gt; '' in Progress: def: Return the render_template (...)   
 The progress in the scene should be accessible only when it is called "from home view" Is it possible?  
 Is it possible?   
 
 
 redirect before, session Set a flag in the object. Check the "progress" view to that flag If this is set, Groove is to present the page. If it is not there, then redirect them to another page (and flash the warning about trying to access that page, alternatively).

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
