fetching images manually from a website that uses a sessionid variable

Hi everone.

I'm trying to write a shell script that fetches a number of images from a
map website (www.whereis.com.au). Basically, the page asks you for a street
address and then queries the server in a strange way, and then displays the
map you asked for. It then allows you to scroll in different directions from
that map.

My aim is to be able to write a program that will take a street address,
query the website, and return the initial map, and the 8 maps around it. The
problem is that I can't figure out how the query works. Here is a little
snippet (which I captured with ethereal). This is the initial request, with
the address "200 arden street randwick":

POST

Now, I can obviously see my search parameters in there, but how would I use
these in lynx to get the initial webpage? Can I just take these all as POST
variables, or is there something I have to do with the sessionid?
thanks,

C# Website - Global Functions

by: David P. Donahue | last post by:

When I wrote websites in VB .NET, I would often put functions in Global for all the pages to call. Now, in C#, doing so results in "references to non-static objects" and whatnot. I realize what that means and all, but what I'm wondering is what's the best way around it? Say, for example, I want a function that takes a username and a password and returns true or false if it's a successful login, and I want any page or usercontrol in the...

Exploring the open sessions, manually connecting one

by: Pavils Jurjans | last post by:

Hello, I have two questions regarding the Session state. 1) Is there some way on the server to programmatically access the other active sessions? Well, perhaps the question should be formulated not "is there a way", but "how to do it", because that almost inevitably must be possible - after all, the ASP.NET enables access for all the session users to their respective sessions. Perhaps studying the full request lifetime, and finding...
