Binding Links in a Custom Object using Upsert function in C# SalesForce?

I have the following code which creates a Task in Salesforce and then tracks a user's browsing history and stores it in SalesForce. Currently, it displays each and every page the user has browsed as an individual entry. I want to group all those entries together in the Browsing_History__c object instead of task being created every time a user visits a page.

Any help would be appreciated..I am not familiar with SF very much. :)

private void CreateTaskInSF(string id, string type, string details, string description)
    {
        // if there's a similar Event in the past 2 hours, don't add it
        QueryResult qr = null;
        try // get events from past 2 hours
        {
            qr = Binding.query("Select Details__c from Task WHERE WhoId='" + id + "' and Type__c='" + type + "' and CreatedDate > " + DateTime.UtcNow.AddHours(-2).ToString("s") + "Z");
        }
        catch (Exception e)
        {
            return;
        }
        bool logged = false;
        if (qr != null) // if there are Tasks in past 2 hours
        {
            sforce.sObject[] browsing = qr.records;
            if (browsing != null)
            {
                // iterate through events to make sure the new Task isn't logged
                for (int i = 0; i < browsing.Length; i++)
                {
                    Task currTask = (Task)browsing[i];
                    if (currTask.Details__c == details)
                    {
                        if (description != "") // is there a description to check for?
                        {

You'll need to update your query to ask for the browsing history object and update the code to create a browsing history object instead of a task.

If you haven't already, review the Web Services API docs, it has examples for querying and creating in java/c#.
