Handle Web Server with multiple clients

阅读更多关于 Handle Web Server with multiple clients

问题 I am working on a web application which can serve only one client.Now I need to include functionality to serve multiple clients. For that one mechanism should be there in which all the clients can see OR will be notified if any changes are done by some another client in the application. So my job is now to notify all the clients once any changes are done from the back end by another client. I found one solution in which I will call one cgi script from javascript at a particular period of time

Subrequest for PHP-CGI

阅读更多关于 Subrequest for PHP-CGI

问题 virtual() can be used only when running PHP as an apache module. My shared hosting runs it as CGI so it doesn't work. Is there any other method to do it? Note: the subrequest is for static files that I'd like to let Apache serve (for performance, HTTP-headers caching, etc.). Right now this is handled by using an HTTP redirect (that I want to get rid of) issued by the PHP script. 回答1: If they're static files, why not just include() them? Forcing apache to make a subrequest seems like a waste.

It is not information easily found on the net. Here is my client code snip: my $bytes_received =

IP address of domain on shared host

阅读更多关于 IP address of domain on shared host

问题 I have domain on a shared hosting provider. How do I find the direct IP address of my domain using Python? Is it possible to post to a script on my domain using the IP address and not the website itself? Thanks. 回答1: I guess the IP should be static so do you really need to look it up more than once? You need to specify the domain name so that the webserver knows which host configuration to use if you don't have a dedicated IP or your host is the default for that webserver 回答2: import socket

Improving the Secuity of a Python CGI Script that Creates User Accounts

阅读更多关于 Improving the Secuity of a Python CGI Script that Creates User Accounts

问题 Below is the code to a CGI script for the creation of user accounts. The script will check if a username for a new account is taken and will, if a the username is not taken, create a file with information (i.e. username and password) about a new user. Previously, a question was asked about giving CGI scripts created by this file certain privileges (link: Running a Python CGI Script with Sudo Privileges on the Apache Server). Feedback was given about potential security problems with this
