            searcher.Filter = "(objectclass=user)";
            try
            {
                searcher.FindOne();
                {

            {
                if (ex.ErrorCode == -2147023570)
                {
                    ex.Message.ToString();
                    // Login or password is incorrect 
                }
            }
        }

Hide the extension .aspx in the url of page ...

Now a days customers are more concerned with site URL and its relative path displayed on the browser address.
Many Suggest having interceptor/handler or use the existing global.asax (Application_Begin Request handler) for modifying the URL shown in the browser window, Web Routing is the concept (4.0 framework)

However you can get solution for .Net /sharepoint application there are following ways:

1. MVC
2. HttpModule rewrite URL
3. ISAPIRewrite to enable Extension-less URL Rewriting for IIS5 and IIS6
4. IIS level extension parsing

Step by step approaches refer below links:

Sandbox Solution: Overview

What is sandbox solution

Sandbox is a restricted environment where programs are deployed with restrictions. It plays valuable role for developers to test their application by using sandbox solution. Once this is tested it can be later deployed to full use in the farm.

Solution that are deployed into sandbox are called sandbox solutions.

 

Advantages

If farm is load balanced.

Release code which is fully not tested for production release.

Less bottleneck for farm administrator as this can be managed at site collection by administrator to it.

Disadvantages

First decide whether you want this solution? as using this solution does has impact on performance of the servers. As the farm using sandbox does have more process load than a farm without this.

Code Access Security (CAS) limits the operations that the code can perform

How to use

Activate SharePoint 2010 User Code Host service(SPUCHostService.exe,)  on server you want this solution. Should be done by farm administrator

Sandbox Code Services

Sandbox can be applied at the root of site collection level.

Members of the site collection administrators group can deploy sandboxed solutions

Governance for sandbox

Before deploying think of below

When should the solution be blocked or unblocked?

When to release the solution to production?

Who should be given access, deployment rights etc?

Adding / Blocking /Load Balancing for Sandbox

This can be done via CA – System settings
