How asp.net MVC's cache and Firefox's cache work? -


I *. To write the cache header on Png requests, I use the following code: response.Buffer = false; Response.BufferOutput = false; 

  // encoding based on the content type and file extension and // whether the response response is compressed. Content Type = Mimmapping GetMimeMapping (physicalFilePath); If (mode! = Response Compression Type. Non) response. Append header ("content-encoding", mode.tostring (.) Toolless ()); reaction. AppendHeader ("content-length", count.ToString ()); // Empty the proper cache header which will cache the response to the // cache of the browser for the default cash duration response. Cash Set cacheability (HTTP capability public); reaction. Cache.AppendCacheExtension ("Mandatory-Certified, Proxy-Modify"); Response.Cache.SetMaxAge (DEFAULT_CACHE_DURATION); Response.Cache.SetExpires (DateTime.Now.Add (DEFAULT_CACHE_DURATION); Response.Cache.SetLastModified (lastModified);

But every time I refresh the page that contains the PNG URL, it will be posted again on the web server. It seems that the cache header does not work, and worse, this browser cache also does not work.

I am using asp.net mvc. Can anyone tell me the right direction? Thanks!

will be a post ever will not be cached If any browser or server requests a POST request from the browser, then the server will be execute it. You can not cache the results post not the only way to do this POST not to be released.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
