content-length

问题 I try to create an application in web2py framework. By default web2py server has Transfer-Encoding: Chunked header for response, but in that case when target remote web application sends GET request to my app it could get only first string of text from requested page (from file's content that displayed on page). If to use Content-Length instead, for example, with value of 1000 it will get 1000 bytes of data from page... But if I expect to response with huge range of data, how to set Content

问题 i am new on Simfony and I am trying to set a Content-Length header in my response. This is my controller action: public function homepageAction() { $content= $this>renderView('AcmeBlogBundle:Pages/homepage:homepage_content.html.twig'); $response= new Response(); $response->setContent($content); $response->headers->set('Content-Length: 1736233495'); // value added manually return $response; } // homepage i obtain an error 500 internal server error. 回答1: Did you try to $response->headers->set(

问题 I'm still struggling to Stream a file to the HTTP response in Pylons. In addition to the original problem, I'm finding that I cannot return the Content-Length header, so that for large files the client cannot estimate how long the download will take. I've tried response.content_length = 12345 and I've tried response.headers['Content-Length'] = 12345 In both cases the HTTP response (viewed in Fiddler) simply does not contain the Content-Length header. How do I get Pylons to return this header?

问题 How to determine the content-data length if the header is not sent and instead you receive Transfer-Encoding: chunked header? 回答1: With chunked encoding there will be no Content-Length header. So after you've read the headers and the pair of CRLFs that mark the end of the headers, you're ready to read the first chunk. Each chunk payload is preceded by its own mini-header - the length in hex followed by CRLF. And there's another CRLF after the payload, before the next chunk's mini-header. A

问题 I am using a PHP script to download a file when you go to a page, but I can't set it up so that when a person downloads the file, it will show the file size (mine shows "unknown time remaining"). I've looked around on Google and can't find out how to make file sizes show up for me, because according to all these scripts I'm doing it right. I have echo'd the filesize to make sure that the script is reading the file properly, and it returns the correct file size in bytes. $file = 'audio/song

问题 I'm trying to speed up the following: string s; //--> s is never null if (s.Length != 0) { <do something> } Problem is, it appears the .Length actually counts the characters in the string, and this is way more work than I need. Anybody have an idea on how to speed this up? Or, is there a way to determine if s[0] exists, w/out checking the rest of the string? 回答1: EDIT: Now that you've provided some more context: Trying to reproduce this, I failed to find a bottleneck in string.Length at all.

问题 I'm setting the length of the content in my HttpURLConnection, for a PUT. urlConnection.setRequestProperty("Content-Length", "" + responseJSONArray.toString(2).getBytes("UTF8").length); The actual number of bytes is 74. However, when I query the content length of urlConnection I'm returned -1 . Why is that? And why are lengths not equal (given that I set this)? I must set the content-length because I'm receiving a 411 response from the server. (Also, in the Sun examples I've seen the second

I'm having an InputStream from a ProcessBuilder that acutally reads the stdout stream. Question: how can I know the size of that inmemory InputStream , so I can write it to a HttpResponse http header?

问题 Has anyone successfully added a Content-Length header to regular ColdFusion (I'm using CF9) pages? I'm setting up a new server behind a Cisco load balancer with compression - the box refuses to compress anything without this header, but CF doesn't pass it by default. <cfheader name="Content-Length" value="something"> will set the header, but finding the right value is a problem. Any pointers would be much appreciated. 回答1: I believe I've solved it: <cfheader name="Content-Length" value="
