http-headers

问题 I am working on a script where after some operation of PHP functions, I generate a base64 image data in $base64Image variable. Now I want to show that base64 image data as a full image on the web browser same as an image.jpeg . For this purpose, I wrote some codes as shown below... screenshot.php <?php /*------------------------ // Basic PHP Operations // ------------------------*/ // Get URL Parameters $key1 = $_GET["key1"]; $key2 = $_GET["key2"]; // Some PHP Operations......................

问题 In one of projects we use CloudFlare and its cf-connecting-ip header to get a visitor IP address. But I'm not sure that the info can be fully trusted. For example, a bad user somehow had obtained real IP of our server, and connecting directly to it, putting fake IP address to the cf-connecting-ip header, and pretending that it was a legitimate CF-proxied request. I examined headers for CF-proxied requests, and saw the cf-request-id header. But it's unique per a request, and I cannot see there

问题 I have a doubt about max-age behaviour after reading the Http Cache rfc. Scenario: User agent GET /foo Origin Server Response header cache-control: max-age=120 Server tells user agent that the resource requested should be revalidated after 2 minutes. After 1 minute and few seconds, User agent makes another request, specifying a max-age of 1 minute: User agent cache-control: max-age=60 GET /foo From what I understand, this request should bypass the user agent cache. Why? Although the Origin

问题 If a response to a GET request doesn't have the Content-Length or Transfer-encoding: chunked field, what happens? How does the client know when the message ends? 回答1: RFC 7230 section 3.3.3 contains a nice checklist of conditions for finding the message body size. Essentially it says the answer depends on what the status code is. The relevant conditions being #1 and #7. "1. Any response ... with a 1xx (Informational), 204 (No Content), or 304 (Not Modified) status code is always terminated by

问题 I would like to mask the version or remove the header altogether. 回答1: To change the 'Server:' http header, in your conf.py file: import gunicorn gunicorn.SERVER_SOFTWARE = 'Microsoft-IIS/6.0' And use an invocation along the lines of gunicorn -c conf.py wsgi:app To remove the header altogether, you can monkey-patch gunicorn by replacing its http response class with a subclass that filters out the header. This might be harmless, but is probably not recommended. Put the following in conf.py:

问题 I've got big problem with my login system in NodeJS. I created login site, when i'm logging in. When i check if login and password is correct i make jwt token. Then i would like to pass it into header and redirect to my user page by get method. I searched a lot of sites and I' cant solve this problem. This is what I try to do: const token = jwt.sign({_id: id}, process.env.TOKEN); res.header('auth-token', token); res.redirect('/admin/admin_panel'); I would like to this work like Postman. I set
