http-status-code-304

ASP.NET MVC 3.0, IIS 7, .NET 4 I have an action that returns data that seldom changes (almost static). Is there an easy way to: return 304 "Not Modified" from action; include "Last-Modified" time stamp in the response. I use return Content('my data'); for action result. Basically I want an easy way to do what is talked about in this article : http://weblogs.asp.net/jeff/archive/2009/07/01/304-your-images-from-a-database.aspx (Very!) late answer but this question pops up near the top in search engine results so it might be useful to future people landing here. Alternative for part 1: return new

Playing around with the Volley library, I noticed that when making a POST JsonObjectRequest , if the server returns a code 304 or 200 with no data in the response (response.data) , Volley interprets it as an error response, instead of a success. I manage to solve it by adding a couple of lines of code in the method Response<JSONObject> parseNetworkResponse(NetworkResponse response) in the class JsonObjectRequest.java . @Override protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) { try { if (!response.notModified) {// Added for 304 response String jsonString = new

I can't find any answer to my question, may be I miss something... When I ask for a url, I need to know if the response comes from the cache or from the net. Is the status code 304 or 200 ? (but AFNetworking always responde 200) With ASIHTTPRequest I used to check " didUseCachedResponse " from ASIHTTPRequest , this was perfect. Darrarski I think I found a solution to determine if response was returned from cache or not using AFNetworking 2.0. I found out that each time a new response is returned from the server (status 200, not 304) the cacheResponseBlock which is a property of

When a web server responds to HttpWebRequest.GetResponse() with HTTP 304 (Not Modified), GetResponse() thows a WebException , which is so very weird to me. Is this by design or am I missing something obvious here? Ok, this seems to be a by-design behavior and a perfect example of a vexing exception . This can be solved with this: public static HttpWebResponse GetHttpResponse(this HttpWebRequest request) { try { return (HttpWebResponse) request.GetResponse(); } catch (WebException ex) { if(ex.Response == null || ex.Status != WebExceptionStatus.ProtocolError) throw; return (HttpWebResponse)ex

When I reload a website made with express, I get a blank page with Safari (not with Chrome) because the NodeJS server sends me a 304 status code. How to solve this? Of course, this could also be just a problem of Safari, but actually it works on all other websites fine, so it has to be a problem on my NodeJS server, too. To generate the pages, I'm using Jade with res.render . Update: It seems like this problem occurs because Safari sends 'cache-control': 'max-age=0' on reload. Update 2: I now have a workaround, but is there a better solution? Workaround: app.get('/:language(' + content

How to check if jQuery.ajax() request header Status is "304 Not Modified"? jqXHR.status usually returns 200 , even when requested header is "304 Not Modified". ifModified:true does not help a lot because it breaks XHR data request. Without handling cache headers manually, it is not possible. Normally, 304 responses are not made available through the XHR API : For 304 Not Modified responses that are a result of a user agent generated conditional request the user agent must act as if the server gave a 200 OK response with the appropriate content . jQuery normally doesn't know there was a 304
