http-headers

问题 Please forgive my lack of understanding on this subject. I had bunch of urls that I am interested to know the size of its web page. So, I used HTTP Head req method to get the Content-Length. I verified the Content-Length values generated from Head method by opening some of those urls in a browser (I used Firefox) and checking the "View Page Info" (from right-click on website in browser) option that gives the "Size:". For most of the urls, both the values matches but not for some. I wonder why

问题 I use Content negotiation to let user-agents select one of several representations for a resource. Example : the resource http://example.com/essay has the following representations: text/html → http://example.com/essay.html application/xhtml+xml → http://example.com/essay.xhtml application/pdf → http://example.com/essay.pdf Let’s say the user-agent selects the HTML variant. Now I could link the other representations with the link relation type alternate: <link rel="alternate" type=

问题 I want to know how to remove the Server header completely that apache sends in the response. Initially, it was showing full server info like Server: Apache (Ubuntu 14.04) in the response headers.

But still no luck. So, I want to remove that completely. Thanks,

问题 I'm building a mac application and not using the AWS iOS SDK. The GET request I'm trying to build should follow this general format: "Authorization: AWS " + AWSAccessKeyId + ":" + base64(hmac-sha1(VERB + "\n" + CONTENT-MD5 + "\n" + CONTENT-TYPE + "\n" + DATE + "\n" + CanonicalizedAmzHeaders + "\n" + CanonicalizedResource)) As provided as "pseudo syntax" in the Amazon docs.

问题 I have a .NET MVC application which is calling a WCF service. I need to include a JWT token in the HTTP header of the MVC application and decode the token in the WCF application. The binding is basicHttpBinding. I would appreciate any suggestions... 回答1: assuming you are inside controller method write : ControllerContext.HttpContext.Response.AddHeader("name","value") 回答2: I finally managed to find a solution and I've sent the token through a SOAP header. For that I just had to add <headers>

问题 Basically, I know of this website http://www.whatsmyuseragent.com but it truncates the user-agents it gathers to 150 chrs. I also know of http://botsvsbrowsers.com but that site (although better) truncates to 200 chrs. I just want a website similar to these ones (any site that shows other users user-agents) but allows for at least 300 chrs or does not truncate them! Also, if you don't know weather the site you have in mind truncates the User-Agent, that's ok. As long as it's a site that lists

问题 I am trying to set a header for a specific file via my htaccess file in order to give my service worker access to my root. Unfortunately I don't see the header appearing... Perhaps I am not targeting the file (https://www.stefanklokgieters.nl/wp-content/themes/stefanklokgieters/serviceworker.js) correctly? # Add custom header to single file <Files "/wp-content/themes/stefanklokgieters/serviceworker.js"> Header set Service-Worker-Allowed "/" </Files> # BEGIN WordPress <IfModule mod_rewrite.c>

问题 I have set my Google Nexus 4 device to the Français (France) setting, and am browsing a site that is localized via the Accept-Language HTTP header from the client. However, when I look at the Accept-Language settings arriving at the server, I see is is just en-US . If I use the Dolphin browser to view the same site on the same device, the header comes in as fr-FR,en-US;q=0.8 , and the site displays correctly in French.
