问题 The funny thing is: I may have accidentally found the solution for Is it possible to send HTTP request using plain socket connection and receive response without headers?. I hope I'm overlooking something. Anyway, I'm connecting to a web server, send a HTTP request, receive the response and close the connection.

阅读更多关于 How can I configure HTTP Response Headers in a Struts2 Interceptor?

问题 We currently have a java web application in the middle of migration from Struts 1 to Struts 2. We would like to configure X-Frame-Options and Content-Security-Policy headers for all our Struts 2 actions. We have a lot of actions and I want to avoid modifying them all separately if at all possible. the idea I currently have is the following interceptor which would be added to the default stack: import javax.servlet.http.HttpServletResponse; import org.apache.struts2.ServletActionContext;

Http headers in Javascript?

阅读更多关于 Http headers in Javascript?

问题 Is it possible to gather the HTTP headers in JavaScript ? This is just a thought of mine after using Firebug for days. In one of the posts I came to know that, it is impossible to find the HTTP headers in JavaScript, whereas in firebug, we can see the response headers (client side) so my question is can we cache the HTTP headers in JavaScript ? 回答1: The HTTP headers aren't available in JavaScript. However you could use XMLHttpRequest to do a HEAD request to any resource within the same domain

Returning http status codes with a rest api

阅读更多关于 Returning http status codes with a rest api

问题 I am building my own rest api in php for practice. I can evaluate the http code sent to my api (post,put,delete,get). But when I send out my response I really am just printing out a json. For example, I build a response in my api like this public function actionTest() { $rtn=array("id":"3","name":"John"); print json_encode($rtn); } I am not manipulating the headers in anyway. From reading stackoverflow, I understand that I should be returning http response codes to match my api results. How

headers_sent() return false, but headers were sent

阅读更多关于 headers_sent() return false, but headers were sent

问题 My code is simple: <!DOCTYPE html> <html> <head> ... <?php var_dump(headers_sent()); ?> It returns false. Shouldn't the headers be sent immediately after something is printed? Like just after the first < character. 回答1: It depends if your output_buffering directive in php.ini file. If it is Off output_buffering = Off then echo headers_sent() should output 1 In other cases, headers_sent() won't output any results because it will be FALSE. The headers won't be sent because the output is

Will iso-8859-1 display german umlauts ok or do I need to use utf-8?

阅读更多关于 Will iso-8859-1 display german umlauts ok or do I need to use utf-8?

问题 I have a multi language website that is hosted on a server that appears to have character encoding set to default to iso-8859-1. I thought I would be best having the pages utf-8 and included a meta tag to declare this. Unfortunately this meta tag seems to get overridden and the page defaults to iso-8859. Many special characters in the German and Dutch pages are not showing correctly. Do I need to try and change the server default to utf-8 or something? Maybe I could remove the server default

How to tell when a web page has changed by x% in VB.net?

阅读更多关于 How to tell when a web page has changed by x% in VB.net?

问题 I'm trying to write a little utility which will check periodically and tell me if/when a web page's (could be any URL) content has changed. I've read the other postings but they don't really answer my question (as far as I can tell). I know for static pages there is a last-modified header. However, what about dynamic pages? I got Oli's comment that storing a hash of the contents works but that's not really idea because the page might simply have a time stamp on it (the date-time that the page
