问题 I'm trying to avoid0 CORS preflight requests for authorized GET requests, for latency performance reasons. The simple way to do that is putting the access token in a URL query parameter, but this is a bad security practice1. According to this answer2, the goal of browsers is to block anything that couldn't already be accomplished with HTML tags like img or script . But if that's the case, why is it allowed to set headers like Accept or Content-Langage ? You can't set those on an img tag. Also

问题 I'm using Java Spring 3.0.4 (can't upgrade due to some requirements) and I need to enable Cors in order for my front-end to talk to my back-end. My back-end is an angular application running on: http://localhost:4200/home I have tried the following with no luck: public static final String CREDENTIALS_NAME = "Access-Control-Allow-Credentials"; public static final String ORIGIN_NAME = "Access-Control-Allow-Origin"; public static final String METHODS_NAME = "Access-Control-Allow-Methods"; public

问题 I know the usual method of specifying a timeout with HTTP requests by doing: httpClient := http.Client{ Timeout: time.Duration(5 * time.Second), } However, I can't seem to figure out how to do the same when tracing HTTP requests. Here is the piece of code I am working with: func timeGet(url string) (httpTimingBreakDown, error) { req, _ := http.NewRequest("GET", url, nil) var start, connect, dns, tlsHandshake time.Time var timingData httpTimingBreakDown timingData.url = url trace := &httptrace

问题 I have a doubt about max-age behaviour after reading the Http Cache rfc. Scenario: User agent GET /foo Origin Server Response header cache-control: max-age=120 Server tells user agent that the resource requested should be revalidated after 2 minutes. After 1 minute and few seconds, User agent makes another request, specifying a max-age of 1 minute: User agent cache-control: max-age=60 GET /foo From what I understand, this request should bypass the user agent cache. Why? Although the Origin

问题 I need to test the following method with out altering the method itself. The method makes a POST method to a server. But I need to make a test case that's independent from the server. I tested a similar method before redirecting it to a local file. But that for that I was giving protocol as file, hostname as localhost and port as -1. My problem is that this method does a post and casts to HttpURLConnection and wr = new DataOutputStream(conn.getOutputStream()); wont work on an local txt file

问题 I have just learned from this questions that Google app Engine now supports session. I would like to be able to use them but am not sure whether I should just because I can. Thanks to scalability issues. My questions are really, Where would I store the session information? In the data store or would this take to long? And surely far to costly? What about the mem cache? I have only known of GAE for a few days and am still reading. Is the Mem cache considered to be fast/scalable and does it

问题 I'm trying to understand the behavior of HTTP referer header. I noticed that sometimes the referer is full (full URL, including path and query string) but mostly it includes the domain only. For example 'https://www.google.com/' instead of 'https://www.google.com/search?q=http+referer+truncated&oq=http+referer+truncated&aqs=chrome..69i57.6485j0j1&sourceid=chrome&ie=UTF-8#q=http+referer+is+not+full' Are there any rules as to when the refere and is full and when it's truncated? 回答1: HTTP
