grails - Passing parameters in Link - Beginner -

-

The code I write to & lt; Link & gt; I'm going through in that case it's too long I can 

  & lt; Td> & Lt; G: link action = "showresult" id = "$ {r.id}" param = "['DNA': r.dnasequence, 'command': r.order]" & gt; $ {FieldValue (Bean: Resultant Field, Field: "Patient ID")} & lt; / G: link & gt; & Lt; / Td> The value for   
  r.dnasequence  is more than 1000 characters long, so it all engages in the URL.  
 How can I send it without including the URL?   
 
 
 You can not send a post request using g: contact. It is better to use AJAX or remote links (deprecated).

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
