What's in an HTTP request? - 0 views

  • These headers tell us which web server you were trying to contact.  If that seems odd, bear in mind that many web sites can be "hosted" on a single server, so when the request is received it needs to know which web site you were attempting to access

  • The request method is usually either "GET" or "POST".  Basically if you fill in and submit a form on a web page it might generate a POST request (or it might be "GET"), whereas if you just click on a link, or activate one of your browser's "bookmarks" or "favourites", then the request method will always be "GET". Therefore, if it's "POST", we can tell that a form was definitely submitted.  The contents of the form would appear here, and there would also be some "Content-" headers describing the data. Web browsers generate two kinds of "POST" data: either "multipart/form-data", which is used when uploading files to a web server, or the more common "application/x-www-form-urlencoded".

  • The "referer" header tells us which document referred you to us - in essence, if you followed a link to get to this page, it is the URL of the page you came from to get here.

  • Connection control Connection:keep-alive Keep-Alive:300 These headers are used to fine-tune the network traffic between you and the web server.  They don't tell us much, except a little about the capabilities of your web browser.

      kan nefsi yekon fe shar7 lel 7eta deh aktar !!
  • Authorisation Username:not present If you have "logged in" to a web site, your username appears here. Note that this only applies to web sites which use proper HTTP authentication - typically, a "login" window pops up and you get three chances to enter your username and password, otherwise you see a page which says "Authentication Required" or similar.  It doesn't apply to web sites where the "login" is a separate page. It's also possible to supply the username and password in the URL you tell your browser to visit - for example, http://user:password@www.example.com/.  In that case, the username would appear here too.

What is Domain Name Resolution - 0 views

  • What is Domain Name Resolution Introduction When using the Internet most people connect to web sites, ftp servers or other Internet servers by connecting to a domain name, as in www.bleepingcomputer.com. Internet applications, though, do not communicate via domain names, but rather using IP addresses, such as 192.168.1.1. Therefore when you type a domain name in your program that you wish to connect to, your application must first convert it to an IP address that it will use to connect to. The way these hostnames are resolved to their mapped IP address is called Domain Name Resolution. On almost all operating systems whether they be Apple, Linux, Unix, Netware, or Windows the majority of resolutions from domain names to IP addresses are done through a procedure called DNS.
    • Ahmed Mansour
       
      i think it's great artical !!
    • Islam TeCNo
       
      Yes .....we know that Web sites are on servers that has IP adresses like this 217.143.56.12 for example .....this article tell us how the site name [www.google.com] is converted to the IP thanks Mans
    • magdy medhat
       
      ya tecno ya gamedddddd mesh de elly kona bntklm feha fel microbus :D
  • Hosts File - There is a file called the HOSTS file that you can use to convert domain names to IP addresses. Entries in the HOSTS file override any mappings that would be resolved via a DNS server
    • Islam TeCNo
       
      I think this is what some spam and adware programs use .... you type a normal site Name but you go yo another site ... i think so !!
  • Netbios - This only applies to Windows machines and will only be used to map names to IP addresses if all previous methods failed. This method will attempt to map the netbios name you are trying to connect to with an IP address.
    • Islam TeCNo
       
      any body can explain this point for me ?
  • ...2 more annotations...
  • This can be changed though by changing certain registry keys
    • Islam TeCNo
       
      start -> run -> regedit this will allow you to edit the registry
  • DnsPriority = 30 LocalPriority = 200 HostsPriority = 75 NetbtPriority = 100
    • Islam TeCNo
       
      Or Simpler DnsPriority = 1 HostsPriority = 2 NetbtPriority = 3 LocalPriority = 4

CodeProject: C# vs C/C++ Performance. Free source code and programming help - 0 views

  • is compiled twice. Once while the program is written and second when the program is executed at the user's site. The first compilation is done by your C# builder and the second by the .NET Framework on the user's machine. The reason why C# compiled applications could be faster is that, during the second compilation, the compiler knows the actual run-time environment and processor type and could generate instructions that targets a specific processor.
  • A well designed C# program is more than 90% as fast as an equivalent "well-designed" C++ program
  • The problem with "not-freeing" the memory at the right time is that the working set of the application increases which increases the number of "page faults"
  • ...1 more annotation...
  • That's a nice question. Except for writing time-critical blocks of code, prefer C#. Write all your algorithmic code in C++ (not VC++ .NET), compile it into a dll and call that using a Dll Interop through C#. This should balance the performance. This technique is not new or not invented by me or anyone. It's similar the old age C programming vs Assembly, where people on one camp fight assembly programming is faster and the other camp stating C is easier to develop and then people started using assembly embedded within a C program for time-critical applications using an asm block.

The Freenet Project - /index - 0 views

  •  
    Freenet is free software which lets you anonymously share files, browse and publish "freesites" (web sites accessible only through Freenet) and chat on forums, without fear of censorship. Freenet is decentralised to make it less vulnerable to attack, and if used in "darknet" mode, where users only connect to their friends, is very difficult to detect. Share files, chat on forums, browse and publish, anonymously and without fear of blocking or censorship! Then connect to your friends for even better security! "
