child process will never end.# Setting MaxRequestsPerChild to a non-zero value has two advantages:#1. It can prevent (accidental) infinite Memory leakage and thus exhaust the memory.#2. A limited life cycle is provided for the process, which helps reduce the number of active processes when server load is reduced. To speed up page reading on the client, we need to install and configure the page compression module mod_deflate. This module has been buil

Once am has done all the work, it should unregister the RM and clean up the resources and exit. 5. Optionally, framework authors may add controlflow between their own clients to report job status andexpose a control plane.7 ConclusionThanks to the decoupling of resource management

apache|server|web| Security (2) Buffer overflow security flaw This method exploits some defects written by the program and causes the program to deviate from the normal flow. The program uses statically allocated memory to hold the request data, and an attacker can send an extra long request to overflow the buffer. Like some Perl-written gateway script that handles user requests. Once the buffer overflows,

protocol that is sponsored by Google and is supported by browsers such as Chrome, Opera, Firefox, and Amazon Silk. One of the bottlenecks of HTTP implementations is that concurrency depends on multiple connections. HTTP pipeline technology can alleviate this problem, but it can only do some multiplexing. In addition, it has been confirmed that because of intermediate interference, the browser can not adopt the pipeline technology. Spdy adds a frame layer over a single connection to multiplex mu
