Umbraco Architecture with query string parameters for document

I have a client web app that I've been asked to make some updates to. I have a small number of development hours to work within so a redesign of the system is not an option at this time.
The app was written using classic asp with logic to pull certain content dynamically from a custom database and to write back certain user actions to the same custom database. There is an admin area for viewing these logged user actions.
At some point in time portions of the web app were migrated to use Umbraco 4 for the cms. I've been tasked with migrating some additional content, that is still being pulled from the original custom database, into the context of the CMS.
The content in question is structured so that the content node's document type points to a special masterpage. The master page has codebehind logic that checks for a query string parameter and uses that parameter to query the database for content specific to that parameter. In then populates one specific section on the page with that content.
The logic also uses the query string parameter when writing user actions back to the custom database.
I need to maintain the url syntax and behavior of writing user actions back to the custom database but move the displayed content specific to that parameter into the CMS somewhere. Where should I place this content in the CMS and how can I access it from those pages via the query string parameter?
Url Examples:
/site_home/Node1/Node2/Node3/
/site_home/Node1/Node2/Node3/?partner=partner1
/site_home/Node1/Node2/Node3/?partner=partner2
/site_home/Node1/Node2/Node3/Review/
/site_home/Node1/Node2/Node3/Review/?partner=partner1
/site_home/Node1/Node2/Node3/Review/?partner=partner2
/site_home/Node1/Node2/Node3/Checkout/
/site_home/Node1/Node2/Node3/Checkout/?partner=partner1
/site_home/Node1/Node2/Node3/Checkout/?partner=partner2

Building a crawler to get the content of page

I'm writing one crawler to get the content of the website, however I have some doubts as following :
one URL which is debugged by Fiddler, in which I need to set some values ( set/get the sessionID, put in the dates...) in this URL with get parameters.
then I have another POST URL which uses the cookie which is contained in above URL in order to produce the content of the page with the date given above.
In C# what I did was, first I run the first URL to parse the ID , second I set the ID get the Session ID (PHPSESSID) , the third step I give the parameters with dates, Fourth, I run the final URL to get the content, but in the last step, it warns me that the date input format might not be correct, and I tried many date format types but still no results.
Is there any relation between those URLs as I did them separatedly, in order to get the content of the page ? I use the same PHPSESSID for each HTTPWebRequest

How to get a javascript array that was created using ClientScriptManager.RegisterArrayDeclaration back to the server?

I'm trying to pass an array of data between JavaScript and code-behind C#. The data is retrieved from a central database and translated to an array on a page by ClientScriptManager.RegisterArrayDeclaration, where the user can edit it.
Now I want to post the data back to the database by code-behind code; but how do I access the modified array on the client-side page again? What's the reverse for RegisterArrayDeclaration, passing the data back from the client to the server?
Thanks in advance!

Combine all array values into a comma-separated string and store that string into a HiddenField value in your client-side JavaScript code. After postback read that hidden field value in server-side code and use String.Split method to get the array.
If you don't want to make a full postback - you can make an AJAX call, sending data in a POST request and reading it on the server via Request("name") method.

Can I pass a .net Object via querystring?

I stucked at a condition , where i need to share values between the pages. I want to share value from Codebehind via little or no javascript. I already have a question here on SO , but using JS. Still did'nt got any result so another approach i am asking.
So I want to know can i pass any .net object in query string. SO that i can unbox it on other end conveniently.
Update
Or is there any JavaScript approach, by passing it to windows modal dialog. or something like that.
What I am doing
What i was doing is that on my parent page load. I am extracting the properties from my class that has values fetched from db. and put it in a Session["mySession"]. Some thing like this.
Session["mySession"] = myClass.myStatus which is List<int>;
Now on one my event that checkbox click event from client side, i am opening a popup. and on its page load, extracting the list and filling the checkbox list on the child page.
Now from here user can modify its selection and close this page. Close is done via a button called save , on which i am iterating through the checked items and again sending it in Session["mySession"].
But the problem is here , when ever i again click on radio button to view the updated values , it displays the previous one. That is , If my total count of list is 3 from the db, and after modification it is 1. After reopening it still displays 3 instead of 1.

Yes, you could but you would have to serialize that value so that it could be encoded as a string. I think a much better approach would be to put the object in session rather than on the URL.

I would so something like this.
var stringNumbers = intNumbers.Select(i => i.ToString()).ToArray();
var qsValue = string.Join(",", stringNumbers);
Request.Redirect("Page.aspx?numbers=" + sqValue);
Keep in mind that if there are too many numbers the query string is not the best option. Also remember that anyone can see the query string so if this data needs to be secure do not use the query string. Keep in mind the suggestions of other posters.
Note
If you are using .NET 4 you can simplify the above code:
var qsValue = string.Join(",", intNumbers);

Make the object serializable and store it in an out-of-process session.
All pages on your web application will then be able to access the object.

you could serialize it and make it printable but you shouldn't
really, you shouldn't
The specification does not dictate a minimum or maximum URL length, but implementation varies by browser and version. For example, Internet Explorer does not support URLs that have more than 2083 characters.[6][7] There is no limit on the number of parameters in a URL; only the raw (as opposed to URL encoded) character length of the URL matters. Web servers may also impose limits on the length of the query string, depending on how the URL and query string is stored. If the URL is too long, the web server fails with the 414 Request-URI Too Long HTTP status code.

I would probably use a cookie to store the object.

Sharepoint Custom Search Results Page using FullTextSQLQuery

I'm trying to create a customized search that displays results based on my FullTextSQLQuery results (i.e. user types 'Foo' clicks Search, my server-side code performs a FullTextSQLQuery bringing back PDF documents that contain 'Foo' in its text).
My question is what will I need to do after getting the results from my query in order to display the results to the user? Will I need to provide my own results aspx page or does SP have something that is out-of-box that I can use to perhaps pass my results along to?

I'm not aware of anything OOTB, but this is a simple matter of transforming the XML results into HTML using an XSL.
