perl - How do you generate website navigation? -

-

I'm interested in how other people handle website navigation is not part of the style or applicability, but part of the generation Most websites have a type of "navigation tree" that is displayed as one or more menu levels - in what form do you save and process this tree? The simple solution is a stable menu template, something like this: 

  & lt; Ul id = "menu" & gt; & Lt; Li & gt; & Lt; A href = "..." & gt; A & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "..." & gt; Two & lt; / A & gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt; A href = "..." & gt; Three & lt; / A & gt; & Lt; / Li & gt; & Lt; / Ul & gt;

But this is not very flexible. You can not easily mark the current page in the menu and there is no easy way to show or hide a part of the menu tree depending on the current page. (Or is this?)

I came up with a navigation tree, something like this: 

 - Title: fruit nodes: - Title: apple - title: orange - title: banana - Title: Music and Content URL: Music Nodes: - Title: Classic - Title: Jazz

This tree is loaded by a special navigation class on parts of the navigation Depending on the current request path, it works a bit better, but still I have other people Sector'm very curious about the solutions.

MySQL deserves an article which I have found earlier that it is invaluable, this dynamic navigation and its boundaries Discusses two common techniques for storing.

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
