How do I clear System.Net client DNS cache?

问题 I'm using the .NET WebRequest while changing my HOSTS file. I'm observing that System.Net doesn't honor those changes - how can I make it do so? I have a number of servers load-balanced behind a single hostname, let's say 'example.com'. I want to target several of them individually, so my program will hard-code the machine-specific IP address in my HOSTS file before sending a request to example.com: 163.56.0.34 example.com For the first server and first request, this works fine. Then my

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . After upgrading to Mac OSX Lion I figured out that /etc/hosts is not looked up in first place for name resolution anymore. This leads to some side effects like: Entries in /etc/hosts are resolved painfully slow You can't not override existing domains, e.g. 127.0.0.1 www.google.com If you get search domain

阅读更多关于 IOError: 13, 'Permission denied' when writing to /etc/hosts via Python

问题 I have a Python app that I'm working on that needs to access the hosts file to append a few lines. Everything worked on my test file, but when I told the program to actually modify my hosts file in /etc/hosts I get IOError 13. From what I understand, my app doesn't have root privileges. My question is, how can I circumnavigate this issue? Is there a way to prompt the user for their password? Would the process be any different if I was running the app on a Windows machine? Here's the code in

How are 127.0.0.1, 0.0.0.0 and localhost different?

阅读更多关于 How are 127.0.0.1, 0.0.0.0 and localhost different?

问题 I don't understand the difference between these terms and how they are connected. I looked at a hosts file on my computer and could see that 127.0.0.1 and localhost are connected but not sure how and I don't know where 0.0.0.0 fits into all this. I've seen other answers to this question but I'm a newbie and the other answers about loopbacks and meta-addresses weren't easy to follow. 回答1: Yes, on your local system localhost does translate into 127.0.0.1, which will always be the IP address of

Prevent Chrome from caching a site's DNS records

阅读更多关于 Prevent Chrome from caching a site's DNS records

问题 Chrome caches DNS records and tends to ignore changes to the hosts file after it has successfully connected to my site (barring a restart). With DNS pre-fetching enabled, it is even more pronounced. Are there any page headers that will instruct Chrome not to cache a site's DNS? Like Cache-Control or a response status like 307 Temporary Redirect ? 回答1: This is probably a real bug in Google Chrome. I created http://crbug.com/65570 to track it, but please add any additional information you can

iPhone: add entry to /etc/hosts without jailbreaking

阅读更多关于 iPhone: add entry to /etc/hosts without jailbreaking

问题 For my development process I need to access a webserver which is behind a VPN and has no DNS entry. What I was doing on 4.x was to edit /etc/hosts on the iPhone, and add it to the hosts file. Now I'm on 5.0 beta, and don't want to jailbreak for now just for this purpose. Is there a way I can add a line to /etc/hosts, just for development purposes (the final, distribution application does not need this hack), without jailbreaking? Can I use other means (declare a fake DNS entry by some unknown
