user-agent

Well, I've been working on an User-Agent based shared-session protection between subdomains. I was extremely surprised that it's been working well until IE 11 preview was released recently. There are 2 subdomains example.com and sub.example.com I've intercepted requests to both domains and it seems that USER-AGENT HTTP Header being sent to each domain is different. Request to example.com has: User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko Request to sub.example.com has: User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727;

I've a task to test different user agents on a URL through automation. I'm using ruby to code, and I've been trying to set an user agent using the following method, but it doesn't seem to recognize the user agent. @http = Net::HTTP.new(URL) response = @http.request_get(URL, {'User-Agent' => useragent}) Is there any other way to do this, or what am I doing wrong? http = Net::HTTP.new("your.site.com", 80) req = Net::HTTP::Get.new("/path/to/the/page.html", {'User-Agent' => 'your_agent'}) response = http.request(req) puts response.body Works great for me. Also another that work for me : require

It keeps running in my mind the last couple of days, but I read some articles about how to make your PHP sessions more secure. Almost all of these articles say that you need to save the useragent in the session WITH an additional salt. Something like this: $fingerprint = md5('SECRET-SALT'.$_SERVER['HTTP_USER_AGENT']); The salt would make it harder for an attacker to hijack or whatever the session. But WHY add a salt every time you would check it like this: md5('SECRET-SALT'.$_SERVER['HTTP_USER_AGENT']) == $_SESSION [ 'fingerprint' ] So WHY would a salt make it more secure, since the attacker

I am quite new to scrapy (and my background is not informatics). I have a website that I cant visit with my local ip, since I am banned, I can visit it using a VPN service on browser. To my spider be able to crawl it I set up a pool of proxies that I have found here http://proxylist.hidemyass.com/ . And with that my spider is able to crawl and scrape items but my doubt is if I have to change the proxy pool list everyday?? Sorry if my question is a dumb one... here my settings.py: BOT_NAME = 'reviews' SPIDER_MODULES = ['reviews.spiders'] NEWSPIDER_MODULE = 'reviews.spiders' DOWNLOAD_DELAY = 1

Just wondering what browser type the VB.NET reads as when it visits a webpage. For instance on my website it shows a break down of all the different browsers that accessed my site. You don't provide much context to your question, but I assume that you're talking about the User Agent string that's sent when you use the WebBrowser control built into the .NET Framework. Because that control just uses Internet Explorer to render the page, you'll see a User Agent string very similar to what you'd find if you visited the page using IE on the same computer. The IE string generically reports itself as

Client-side user agent detection is known to be bad and discouraged in favor of feature detection . However, is it also bad to react differently based on the incoming user agent field in a HTTP request ? An example would be sending smaller or larger images based on whether the incoming user agent is mobile or desktop. I think it depends what your motivation is. For example, in the mobile web sector what you are attempting to do is provide the user with something that looks sensible on their platform. Why be concerned about what user-agent the user is reporting, when it is purely for their own

When sending a HTTP request, IE sends the User-Agent variable to the server. A possible value (as seen by the network debugger): User-Agent: Mozilla /5.0 (Compatible MSIE 9.0;Windows NT 6.1;WOW64; Trident/5.0) My question: How does IE (or any other browser) find out this variable? I'm asking this because when visiting some websites, this variable is different than others and I'd like to trace where the change is coming from. 'Compatibility settings' is one option, but I think there is more to it. Can anyone explain the process of this variable? The User-Agent appears in an HTTP Request Header,
