问题 I would like to POST (send) some form data to a webserver using cURL on a terminal-prompt. This is what I got so far: curl --data-ascii "content=derinhält&date=asdf" http://myserverurl.com/api/v1/somemethod The problem is that the umlaute ("äöü") are replaced by "?" when I receive the post request on the server. I think I need to use an UTF-8 encoding for the POST request. Does anybody know how I can achieve this? 回答1: You CAN use UTF-8 in the POST request, all you need is to specify the

问题 How do I test if memcache or memcached (for PHP) is installed on my Apache webserver?

Ultimately, check whether the Memcache class exists or not. e.g. if(class_exists('Memcache')){ // Memcache is enabled. } 回答2: why not use the extension_loaded() function? 回答3: Use this

问题 What is use of these two directories in apache2 and how can we do it? 回答1: The difference is that virtual sites listed in the sites-enabled directory are served by apache. In the sites-available directory there are the virtual sites that exist on your server but people can't access them because they are not enabled yet. sites-available: this directory has configuration files for Apache2 Virtual Hosts.

问题 I try to write a webserver. As far as I am, it works quiet good with Windows. But I want to make it also Unix compatible. And I think there has to be a problem with the heredity f the exception class. For better understanding, just the important parts: server.cpp #include <exception> #include <stdexcept> #ifdef __unix__ #include "UnixSocket.h" #elif __WIN32__ || _MSC_VER #include "WinSocket.h" #endif #include "HTTPParser.h" int main(void) { try { socket->socketInit(PORT); } catch (exception

问题 We have a web application that is storing all the site data in HttpRuntime.Cache . We now need to deploy the application across 2 load balanced web servers. This being the case, each web server will have its own cache, which is not ideal because if a user requests data from webserver1 it will be cached, but there next request might go to webserver2, and the data that their previous request cached won't be available. Is it possible to use a shared-cache provider to share the HttpRuntime.Cache

问题 I have written a small custom web server application in C running on Linux. When the application receives a request it calls fork() and handles the request in a separate process, which is chrooted into a specific directory containing the files I want to make available. I want to port the application to Windows, but neither fork() nor chroot() are available on this platform, and there don't seem to be any direct equivalents. Can you point me to a simple (and preferably well written) example of
