Defining page hints

A page hint tells the system to always treat the URL as the start of a new page. URLs matching the page hint will never be treated as components of another page. If a page download is in progress when this URL appears in the traffic, that page download will be considered complete.

To define page hints:
1
On the URLs > Hints page, click Add a Page Hint.
The Page Hint window displays.
2
In the Hint box, enter the regular expression that is matched against incoming URLs.
3
Click OK.
You are returned to the URLs > Hints page, and your hint is now listed in the Page section.
For information about testing page hints, see Testing hints.

Defining hit hints

A hit hint tells the system to always treat the URL as a hit rather than a page. URLs matching a hit hint are never considered to be the start of a new page download. When these URLs appear in the traffic they do not cause the system to consider an ongoing page download to be complete. If a page download is in progress, these URLs are treated as components of that page download. Defining a hit hint is similar to creating a page hint.

To define hit hints:
1
On the URLs > Hints page, click Add a Hit Hint.
The Hit Hint window displays.
2
In the Hint box, enter the regular expression that will be matched against incoming URLs.
3
Click OK.
You are returned to the URLs > Hints page, and your hint is now listed in the Hit section.

Defining asynchronous page hints

An asynchronous page hint tells the system how to recognize asynchronous URL requests that are commonly used in Rich Internet Applications (RIAs) to enhance interactivity of a web application without requiring a full page download. Ajax (asynchronous JavaScript and XML), or AJAX, is a group of interrelated web development techniques commonly used by RIAs to enhance interactivity. A primary characteristic of RIAs is the increased responsiveness of web pages achieved by exchanging small amounts of data with the server so that entire web pages do not have to be reloaded each time there is a need to retrieve data from the server. This is intended to increase the web page's interactivity, speed, functionality and usability. Ajax is asynchronous, in that extra data is requested from the server and loaded in the background without interfering with the display and behavior of the existing page.

By defining an asynchronous page hint for a set of URLs, you tell the system to effectively treat these URLs as standalone pages. When these URLs are seen in the traffic they do not affect the analysis of any existing page downloads. They are treated as the start of a new page download and do not cause an existing page download to be considered complete. In addition, these URLs are not treated as page components of an existing page (in contrast to a hit hint).

To define Asynchronous hints:
1
On the Configure > URLs > Hints page, click Add an Asynchronous Page Hint.
The Hit Hint window is displayed.
2
In the URLs > Hint box, enter the regular expression that will be matched against incoming URLs.
3
Do one of the following:
•
In the Hint box, enter the regular expression that will be matched against incoming URLs.
OR
•
In the Tag box, enter the HTTP header with a value that will be matched against incoming URLs. In the Value box, enter a value for the HTTP header that you want match against.
4
Click OK.
5
You are returned to the URLs > Hints page, and your hint is now listed in the Asynchronous Page Hint section.

Defining asynchronous hit hints

By defining an asynchronous hit hints for a set of URLs, you tell the system to effectively treat these URLs as a hit rather than a page. For a general explanation about Rich Internet Applications (RIAs) and Ajax (asynchronous JavaScript and XML), see Defining asynchronous page hints.

URLs matching an asynchronous hit hint are never considered to be the start of a new page download. Asynchronous hit hints are always excluded from page download metrics. The asynchronous hit hints will display as individual Hit category metrics but do not display in the Page category metrics.

To define Asynchronous hit hints:
1
On the Configure > URLs > Hints page, click Add an Asynchronous Hit Hint.
The Hit Hint window is displayed:
2
In the Hint box, enter the regular expression that will be matched against incoming URLs.
3
Do one of the following:
•
In the Hint box, enter the regular expression that will be matched against incoming URLs.
OR
•
In the Tag box, enter the HTTP header with a value that will be matched against incoming URLs. In the Value box, enter a value for the HTTP header that you want matched against.

Click OK.

You are returned to the Hints page, and your hint is now listed in the Asynchronous Hit Hint section.
