memory - Share variables between hosts with Go -

-

I have an application in Golong, and this will load basic data globally, so that the application responds faster Create and export a http interface to update the version while the user changes the database.

But I launch another server, and I use a proxy. There is a problem, when the user sends an update URL to the URL, it will load the traffic from any of the servers. Not others

utils.go: 

  Basic data map to package utilities [string] * MyModel func UpdateVar () {// some work} func PreLoadVar () { // preload data in original data}   
 and main.Go  
  package main import ("codebase / utils") func main () {Utils. PreLoadVar ()}   
 So is there any sharing between multiple hosts? Or can any worker help in this work?  
 Nsq.io is a good option, but if I think I want one more simpler. Thank you :)   
 
 
 Your global variable is a very simple form, which is known to be problematic when There are several ways to fix this problem: There are several ways to fix this problem:  
     
  1.  As suggested by Bill Nelson: Using your database as a central database And do not cache your data in your data.  
  2.  Open your cache externally with a simple key-value store, for example by using any one.  
  3.  Use a distributed cache such as.   
     If you have a lot of time on your hands, then  may be  use a message solution like NSQ to implement your distributed cache, but I I will advise against this - this is not an easy problem.

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
