How to implement schema.org on https pages
tl;dr: Use http URIs. In this answer on Webmasters SE I explained why you should favor http over https Schema.org URIs: The http URIs seem to be canonical, as the actual definition of the Schema.org vocabulary only defines http, not https. In addition: all examples (even on HTTPS) use the HTTP variant, the authors mentioned that they prefer to see the use of the HTTP variant, and RDFa’s Initial

gwan dynamic buffer, how often to use and when should you not use it?
As an application server, G-WAN is expected to generate dynamic contents. In this case, the server is building a reply served to clients. Part of these dynamic contents are binary (like pictures) and this is why G-WAN offers a native ultra-fast in-memory GIF, charts, and frame-buffer API. More complex images can be generated with general-purpose libraries like Cairo (used by Internet browsers).

HTTP restriction: oversized cookie
I found the solution by just looking at the response headers locally using Chrome devtools. I realized that Flask sessions are built on top of cookies which caused the oversizing issue (see here). I just got rid of it and now everything works fine.

Does a HTTP resource that accepts range requests always specify content-length?
No. As per any other response with a 200 status code, such a response SHOULD (in the RFC 2119 sense of "SHOULD" which can be summarised as "better have a damn good reason why not, and be able to say what that damn good reason is") include a length (RFC 2616 §14.13) bar a few scenarios in which it is prohibited (§4.4) (in particular, the value must be both the entity and transfer length and as s

Do we need to follow http accept header on an error?
From https://tools.ietf.org/html/rfc7231#section-6.5: the server SHOULD send a representation containing an explanation of the error situation What this means is that the body of the response should contain the error, and the Content-Type identifies its type. For example, by default Tomcat returns an HTML page, so the Content-Type is set appropriately (to text/html, I believe). If your erro

Go http.Request Header on Redirect and Proxy
I looked briefly at the code, at it looks like goproxy doesn't handle 3XX responses in any special way – they're simply routed back to your client, so it can react accordingly. In your case, you'll issue another request with all the headers set. If it wasn't your concern and you were just wondering if simply existence of proxy requires any hack on the client side, then no, http.Client won't rem

request.getParameter() fails on correctly encoded URL
request.setCharacterEncoding( "UTF-8" ); has no effect on doGet() . In doGet() the queryString gets parsed by the container before it reaches doGet() . You should use doPost and request.getInputStream() and parse the queryString yourself. And do not use request.getParameter() before request.getInputStream() or it won't work. Edit Java by default encodes String in utf-16 .. So you will have to

Digest Authentication not working in JMeter
Realm should not be required for digest authentication, domain is quite enough Make sure that you're using either HttpClient3.1 or HttpClient4 implementation See Windows Authentication with Apache JMeter guide for details on how to configure HTTP Authorization Manager for digest and kerberos authentication types

What is the difference between Etag and Expires header?
For what you have described It is clear that ETag works as it expected to be by responding with 304 not modified for the request with If-None-Match field and ETag value. so now the browser will load the image from cache instead of getting a new image from server costing bandwidth and time. It seems that caching is disabled in your browser.That's why a new request has been sent before the cache

Are all spiders supposed to use +http in their user agent string?
It's just a convention that some spiders follow. There is no constraint on what people can put in a user agent header. Take a look at this list of user agents that contain "GoogleBot". You'll notice that many of these don't contain "+http".

Abort HTTP chunk encoded response with Error Page
Unfortunately, there is no chunk you can send that says to the browser "Hey, forget everything I sent so far - something went wrong". Sending a TCP reset packet will cause most browsers to display a "Server reset connection" page, but that requires access to one level down the network stack. The only other I can think of is to try sending a chunk with a negative length. I don't know how browser

Browser image caching confusion
The Cache-Control value is the one that will be used - the image will expire from the cache after 604800 seconds. See this question for more detail. See also here: When both Cache-Control and Expires are present, Cache-Control takes precedence

How to prevent Denial of Service (DoS) using IIS?
DOS attacks cannot be prevented at web server level. It requires a commercial firewall, or cloud based services such as CloudFlare. Like you discovered, manual configuration on IIS, or any simple scripting won't save you from that.

Golang negroni and http.NewServeMux() issue
I am not sure what sure what is the problem with this code, but it appears to be not the negorni way. negroni might not behave as expected if we wrap its handler with another http.Handlerfunc. So, I modified my code and got the work done by middleware. My current code looks something like as below: mux := http.NewServeMux() mux.HandleFunc("/", func(w http.ResponseWriter, req

Unable to get http header
By default, the Authorization header is removed by the Authentication handler. That's why you cant' seem to access it or log it. Handlers act before the mediation inSequence. The Authentication header can be preserved by editing the api-manager.xml config file in /repository/conf. Simply uncomment the following node and change the value to false: <RemoveOAuthHeadersFromOutMessage>false&
