Adding Robots Files to your Web Site - Web Spiders

In this article we see step by step adding Robots Files to your Web Site. Web Spiders are usually called "Robots", and at the moment of accessing a web page, they are called "User-agents".
A Robots file is a suggestion or request made by you to the Web Spider, to not to index certain files or folders in your web site.
It is important to realize that the directives inside the resultant Robots.txt file are purely advisory for the web crawlers.

Adding Robots Files to your Web Site

Before we see step by step how to make a Robots file, take a look at the basics of the Robots syntax with this examples:

all robots can enter all files:
User-agent: *
Allow: /


all robots cannot enter some files:
User-agent:*
Disallow:/file1.aspx
Disallow:/file2.html


all robots cannot enter some directories:
User-agent:*
Disallow:/PrivateDirectory/

some robots cannot enter some directories:
User-agent:SomeRobot
Disallow:/PrivateDirectory/

After this short introduction, let's add a Robots file.

Adding Robots Files to your Web Site - Web Spiders

Open the IIS (CTRL-R + "inetmgr") , then open your web site and click on the SEO - Search Engine Optimization:

First you have to add a Sitemap, if you don't have one:

After you created a new Sitemap, click on "Add a new disallow rule":

Here select the URLs of the files and directories that you don't want to index:

For example:

Now let's add the request to index our web site:

Select the whole web site to be indexed:

Now let's see our rules:

As you see, ALL User-agents are ALLOWED to index our site, except for the Disallow rules:

Now let's see the txt file just automatically created:

 It looks as this:

That's all!!!! The same way, you could select all files or folders for exclusion from indexers.

You can learn about the free IIS SEO Toolkit , and how to install, analyze and optimize your web site, in this tutorial.

How to get 50 GB of FREE High-speed Secure Storage on the Cloud

This post is about How to get 50 GB of FREE High-speed Secure Storage on the Cloud, using the Mega storage service , which is very fast and very secure, and count as the more big , fast and secure FREE Cloud Storage by the date we're writing this article.
We'll use the 50 GB FREE cloud storage offer from Mega , not just because it's fast and secure, but also because it can synchronize folders on our machines, and because has private encryption, deleted files recovery, files versioning, and also offers very good mobile apps.
By the time we write this, Dropbox and SpiderOak  are offering 2 GB of free storage, Box 10 GB, Google 15 GB   shared between Gmail, Google Drive and other services, Microsoft's OneDrive (SkyDrive) and Copy (Barracuda Networks) offer also 15 GB, and BitCasa just 20 GB .
Tencent Weiyun is now offering 10 TB free storage , and you can take a look at their web site. But at first the UI is in chinese, and security matters are far more developed on Mega.
As Dropbox and other storage services, Mega has a folder's synchronization virtual drive, but it's better since it can be configured to synchronize not only one single folder, but any folders we want.
At Mega Storage Cloud, we can share any folder to whoever we want,  also setting permissions  for readonly, readwrite or full access. This way, we can give read-write permissions to a co-worker, which will be required to have another (FREE) Mega account. However, if we intend to share publicly some file, this won't require the downloaders to hold Mega accounts.
The Mega Storage Cloud is very fast: there are reports of 10 Mbps for uploadings, and ~30 Mbps for downloadings.
Mega security is far stronger than other Cloud Storages: all files and data are stored fully encrypted in the cloud , and they are decrypted only in the downloader machine, yours or whoever's you shared your data with. The master encryption key is based on your personal password: be very careful to save it in a safe place, because if lost, all your data is lost.
Restoring deleted files is as easy like to selecting them from the "Rubbish Bin", where our deleted files are kept, and selecting restore.

 How to get 50 GB of FREE High-speed Secure Storage on the Cloud

First , we create a FREE personal account in the Mega web site:

Then, you'll have to confirm your account from your email personal account:

You can select the FREE 50 GB account, or some account more suited to your necessities:

After you confirmed your account, you are exposed to the Mega UI:

The "Cloud Drive" is the place where all our files are stored. The "Rubbish Bin" is where our deleted files are saved, and the "Contacts" are the emails of the people which we shared files with:

You then can proceed to you first upload.

You'll be surprised of the speed and security of this Cloud Storage.

 Enjoy!!!!

Step by step how to send an HTTP PUT Request to a RESTful WCF Service using Fiddler

In this post we'll learn how to send an HTTP PUT Request to a RESTful WCF application using Fiddler. 
We'll use Fiddler to test an RESTful WCF application, sending an HTTP PUT request. We'll start with a working WCF application,  and we'll update an entry using Fiddler, showing as follows :



First of all, we have to download the FREE Fiddler tool from this web site :



After installing it , study the settings of the Operation Contract at the WCF Service Contract, in order to fill exactly what it is expecting as a request:

The WebInvoke handles the PUT HTTP verb, and the request format must be JSON, and so the response format. Therefore, we'll send exactly what the WCF wants.
Open Fiddler and click the "Composer" option:




Then type in the URL and select "PUT" HTTP request method from the list. Also, set the request Headers as follows: (don't worry about the Content-Length, because Fiddler will fill  it for you):

Also, fill the Request Body :  be careful to fill adequately the field names of the Entity you want to update, most of all, the ID of the record to change.

Press the "EXECUTE" button at the Fiddler Composer, to send the request. If you set a breakpoint inside the WCF HTTP PUT handler, you'll see the bindings in action :

As you see, WCF succeeded at binding the JSON it got with the Blog object expected.
The response is then sent to Fiddler, with an "true" value:

And the database shows the updated values:

If you want to take a look at the RESTful WCF which we're using here, see this tutorial.

That's all... 

In this tutorial we've learned how to send an HTTP PUT Request to a RESTful WCF application using Fiddler. 
Happy programming.....

How to use ExecuteStoreQuery with parameters on the Entity Framework

This tutorial is an example of  How to use the ExecuteStoreQuery method with parameters on the  Entity Framework, thus directly executing SQL commands against the Model Data Source.
We'll use a stored procedure that takes in a string parameter and returns some records, which we'll store inside a generic List<>. Using SQL commands or stored procedures is an effective way to retrieve only the records that you need, instead of fetching ALL the table data, to apply on it some kind of filtering using Where() or Single() methods, with all the performance costs that this later imply.

We'll exemplify running commands against the database on two ways:
1) using Stored Procedures
2) using an SQL command

 How to use ExecuteStoreQuery with parameters on the Entity Framework

1) For our first example, we create a stored procedure which takes a parameter and return three records using the received argument:

Next, we define an SqlParameter for sending some text to the procedure:

 SqlParameter p_code = new SqlParameter("code", "TEST");
            List<string> resultComplaintStateCode =
                                (from c in  Context
                                     .ExecuteStoreQuery<string>("GetText @code" ,p_code
                                 )
                                 select c).ToList();

 Notice that we use Linq to insert the returned records inside a generic List<> :

Is really straightforward. However, if you use ExecuteMethodCall() method instead of ExecuteStoreQuery(), you'll need to update the Entity Framework Data Model, importing the stored procedure:

2) As the ExecuteStoreQuery method's name implies, we can also use it to execute some SQL command against the database.
For instance, let's copy the same SQL code from the stored procedure, and execute it directly from the C# code:

 As you see, the SQL command was executed according to the three parameters that we sent :

That's all!!!!
