http-headers

问题 So I'm working on a networking assignment to produce a basic HTTP/1.0 web server in C. I have most of it figured out, but one of the requirements is that it properly populate the Content-Type field in the header, and I can't seem to find any way to do this automatically. I'm already using fstat() to get the file size and when it was last modified, and I noticed that also includes a "st_objtype" field, but after some research it looks like this is just the AS/400 object type (which is

问题 I get a file url,for example, http://cidian.youdao.com/download/YoudaoDict.exe how can I get it's version but not download it ? nots 1: if you download the file first on your computer,there are many ways to get it's version, for example ,you can use the window tools "filever.exe" to get the version. but i want to not download it ,at least not download it all.how can I do? Waiting your help! thanks. nots 2: I have tried the way to get a portion of the file to get the version: first, I used the

问题 I'm securing my page using a csp headers. I set both X-Content-Security-Policy and X-Webkit-CSP . to the following value: default-src 'self'; object-src 'none'; frame-src 'self' *.youtube.com; style-src 'self' https://ajax.googleapis.com; script-src 'self' https://ajax.googleapis.com; report-uri /csp_report Everything loads fine, but I get tHe following error in chrome. I have yet to test it in other browsers. Refused to apply inline style because it violates the following Content Security

问题 I want to set a far future Expires headers to reduce requests made from individual browsers. I'd also like to set Cache-Control: s-maxage=600 so that proxy caches (and CDNs) revalidate with the origin every 10 minutes for fresh content. Will browsers honour the Expires header despite the existence of a Cache-Control header (which supposedly supersedes it) with a s-maxage directive? 回答1: If a response includes both an Expires and a Cache-Control max-age directive, the max-age overrides the

问题 I'm trying to show an HTTP error document from a PHP page, but I would like the original URL to remain in the address bar to prevent search engine crawlers getting confused and to allow for reloading of the page in case it's a temporary issue. I made a redirect function in PHP which goes a bit like this: public static function Redirect($url, $code = '303 See Other') { header('HTTP/1.1 ' . $code); header('Location: ' . $url); exit(0); } If I want to display an error document, such as 403

问题 Is there a way to output the raw html of a CFHTTP call? I am trying to see how some of the header authentication information is coming across. I am open to browser plugins or code updates whichever helps me see what is going on during the cfhttp call. So for example: <cfhttp method="get" url="https://test-ows01.mywebsite.com/criminal_api//1.0/service/requests" result="orderList"> <cfhttpparam type="HEADER" name="Authorization" value="Basic #ToBase64("bearer:4EC8B09D3F911764B1DCD3EFA38DFB31")#

问题 Is something like this possible? <script src="http://myserver.com/some.js" my-custom-header="foo"></script> Update (a bit more detail): I've been asked if there was a way to communicate some parameters to the server as part of the script request using headers instead of GET params. I said, "no," but thought I'd double check. 回答1: Short answer: no. By default a script tag will just retrieve the resource specified in the src attribute. However, if you use an AJAX request to retrieve the script

问题 I'm using PHP to create a CSV file from a database query. I run the query, set the headers, and load the page up in Firefox and the file promps for download and opens in excel just like it's supposed to. When I try it in IE, I get an error saying Internet Explorer cannot download ReportPrint.php from www.website.com. Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. Not sure what can be done to fix

问题 Wikipedia seems to imply that <meta http-equiv> in a web page causes the server to update the response header, but that doesn't sound right to me since the server would have to parse the document before it's sent. That would be fugly. But, I'm having trouble finding much on what does happen when when <meta http-equiv> is used. It seems likely to me that the client parses the page and clobbers anything that was sent in the HTTP header if a <meta http-equiv> tag is found conflicts with the
