http-headers

问题 We are building a Restful service using Grails framework and are providing security for it using Spring Security plugin. I wanted to check with you all on best approach to take when you want to authenticate using Custom Authorization header. More on this approach can be read here Custom HTTP Authorization Header In my case, client id and secret is stored in Ldap and header comes with SHA1 encryption. What would be the best approach to implement this using Spring Security? I have asked same

问题 I am trying to configure CORS globally via WebMvcConfigurerAdapter shown below. To test I am hitting my API endpoint via a small node app I created to emulate an external service. When I try this approach the response does not contain the correct headers and fails with XMLHttpRequest cannot load http://localhost:8080/api/query/1121. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:333' is therefore not allowed access. Global Config import

问题 I have a weird quirk with cookies in IE. When a user logs into the site, I'm generating a new session id and hence need to overwrite the cookie. The flow is basically: Client goes to https://secure.example.com/users/login page, automatically receiving a session id Client POSTs login credentials to same address Client receives the following set-cookie headers together with a 302 redirect to https://secure.example.com/users/mypage : CAKEPHP=deleted; expires=Sun, 05-Apr-2009 04:50:35 GMT; path=/

问题 I am working with an embedded platform that has 16MB of RAM only. And I need to deep packet filter HTTP streams. To prevent a Denial of Service attack on the device I'd like some statistical averages regarding HTTP stream sizes, specifically the HTTP header in particular. 回答1: From Google's SPDY research project whitepaper Uncompressed request and response headers. Request headers today vary in size from ~200 bytes to over 2KB . As applications use more cookies and user agents expand features

问题 Starting recently, some of my new web pages (XHTML 1.1) are setup to do a regex of the request header Accept and send the right HTTP response headers if the user agent accepts XML (Firefox and Safari do). IE (or any other browser that doesn't accept it) will just get the plain text/html content type. Will Google bot (or any other search bot) have any problems with this? Is there any negatives to my approach I have looked over? Would you think this header sniffer would have much effect on

问题 As far as I see, there's no RESTful way to apply a modification to a resource. In order to do it, you have to PUT the resource as a whole, overwriting the previous representation. I think this is source of problems, in particular when the resource has a large representation. I believe this hints at the lack of a verb in HTTP1.1 : something like MODIFY, or PATCH. Not even WebDAV has this verb (it has PROPPATCH, whose concept is similar, but not for the resources). Isn't the current HTTP 1.1

问题 I am making an API where in the access token for Facebook login will be sent in through header data. How do I read this data from the header? 回答1: request.headers["Content-Type"] # => "text/plain" replace "Content-Type" with the name of the header that you want to read. Update for Rails 4.2 There are 2 ways to get them in Rails 4.2: Old way (still working): request.headers["Cookie"] New way: request.headers["HTTP_COOKIE"] To get a Hash with all headers of the request. request.headers 回答2:

问题 I am attempting to create a REST API in PHP and I'd like to implement an authentication scheme similar to Amazon's S3 approach. This involves setting a custom 'Authorization' header in the request. I had thought I would be able to access the header with $_SERVER['HTTP_AUTHORIZATION'], but it's nowhere to be found in var_dump($_SERVER). The apache_request_headers() function would solve my problem, but my host implements PHP as CGI, so it's unavailable. Is there another way I can access the

问题 I'm trying to use axios for a GET request with an API which requires an Authorization header. My current code: const AuthStr = 'Bearer ' + USER_TOKEN; where USER_TOKEN is the access token needed. This string concatenation may be the issue as if I post this as AuthStr = 'Bearer 41839y750138-391' , the following GET request works and returns the data I'm after. axios.get(URL, { 'headers': { 'Authorization': AuthStr } }) .then((response => { console.log(response.data); }) .catch((error) => {

问题 If a HTTP response that returns both Expires and max-age indications which one is used? Cache-Control: max-age=3600 Expires: Tue, 15 May 2008 07:19:00 GMT Considering that each one refers to a different point in time. 回答1: See this answer: Difference between three .htaccess expire rules If a response includes both an Expires header and a max-age directive, the max-age directive overrides the Expires header , even if the Expires header is more restrictive. This rule allows an origin server to
