IE blocking Iframe Cookies

iFramed content that is hosted in a separate domain from the parent page is regarded as third-party content. So due to security constraints, IE block the cookie in an iframe. To overcome this we need to create a P3P policy file. The below links give more details on this.

MySQL Query log

The server writes information to this log when clients connect or disconnect, and it logs each SQL statement received from clients. The general query log can be very useful when you suspect an error in a client and want to know exactly what the client sent to mysqld.

prototype js breaks javascript for in loops

The for in statement allows for looping through the names of all of the properties of an object. Unfortunately, it also loops through all of the properties that were inherited through the prototype chain. This has the bad side effect of serving up method functions when the interest is in data properties. If a program is written without awareness of this situation, then it can fail. So always wrap the body of a for loop inside an if statement by adding a hasOwnProperty condition.

Cookies and localhost

No matter how hard you try, cookies will never be stored in localhost if you explicitly specify the domain parameter as "domain=localhost". Because for the cookie to be stored the domain name must have at least two (2) or three (3) periods in them.
Reference:
You can find here the other conditions for the cookies

Iframe and allowtransparency

For the option allowtransparency="true" to work in an iframe, we need to set the 'style="background-color:transparent"' in the body tag.

Detecting undefined object property - Javascript

while checking the top.location.search object against unknown works smoothly in other browsers except Chrome and Safari. Finally found that we need to check the object for undefined also. So to make it work fine for all the browsers check the object always for undefined and unknown.
(typeof top.location.search!='undefined' && typeof top.location.search != 'unknown')

CName Omniture

A CNAME record or Canonical Name record is a type of resource record in the Domain Name System (DNS) that specifies that the domain name is an alias of another, canonical domain name.
Most of the browsers reject third party cookies, so it is difficult for the analytics to collect the data.
So Omniture decided to use first party cookies. For this we need to create CName record and assign it to the
Omniture trackingServer variable.

Create TinyURL with PHP

Creating a tiny url is so simple, we just need to pass the url as a query string to the following tinyurl api url
e.g   -  http://tinyurl.com/api-create.php?url=http://www.google.com, hitting this in the browser address bar will give the result

http://tinyurl.com/1c2.

Document write disadvantages

The document.write has the following disadvantages

A few of the more serious problems:

• document.write (henceforth DW) does not work in XHTML
• DW executed after the page has finished loading will overwrite the page, or write a new page, or not work
• DW executes where encountered: it cannot inject at a given node point
• DW is effectively writing serialised text which is not the way the DOM works conceptually, and is an easy way to create bugs (.innerHTML has the same problem)
