I want to build a similar app like this:http://community.livejournal.com/ohnotheydidnt/32551171.html
using a livejournal rss feed. Any way of retrieving an external feed ( meaning getting a feed from a different domain that the one your web application-Same origin policy)? I've built a parser, but I would like to use dashcode for simple html building.
Across domains, if the data is only available via RSS and you don't have control of the other domain, then your best option is a server-side proxy.
If you have control over the other domain, you can create a page containing a javascript function which uses XmlHttpRequest to pull the RSS and returns the RSS. Then you can use a cross-domain messaging library like EasyXDM to call that script.
You also might want to check if the RSS feed's website supports JSONP as an alternate format, which would allow you to get the RSS data via javascript. Make sure you trust the site if you do this, though, since the site can execute javascript inside your page!

How can I track that someone visited the following URL of my website http://www.website.com/mypdf.pdf.
I tried using a Page View trigger on a Page View tag. I'm completely new at Google Analytics so not sure how to proceed. Most people are going to be going to that pdf directly via URL, as there is no link to it on my website, but I really want to be able to track how many people view it.
Thanks in advance!
You cannot track PDF views with the help of GTM. GTM for web is a javascript injector, and one cannot inject Javascript into a PDF document from the browser.
One way to circumvent this is to have a gateway page, i.e. have the click go to a HTML page that counts the view before redirecting to the document in question (naturally you could use GTM in that page). Since people go directly to the PDF URL this would require a bit of scripting - you would have to redirect all PDF links to your gateway page via a server directive, count the view and then have the page load the respective document.
Another even more roundabout way would be to parse your server log files and send PDF requests to GA via the measurement protocol (actually many servers allow to have log writes redirected to another script, so you could do this in realtime). I would not really recommend that approach - it's technologically interesting, but probably more effort than it is worth.
The short version is, if you are not comfortable fiddling a little with your server setup you will probably not be able to track pdf views. GTM does not work on PDF files.
Facing same issue…
My solution was to use url shortener (like bitly.com) which includes opening statistics.
Not the perfect solution but it works for direct pdf access from external source (outside your site).
I m developing a Single Page Application (SPA). So, I use to refresh the page's HTML's content dynamically using Ajax requests.
I'd like to register to the DoubleClick for Publishers program, but I m wondering if my SPA is able to integrate advertising due to its dynamic content loaded without refreshing the page.
I saw this link: https://support.google.com/dfp_sb/answer/3058726
So I assume it's ok. But I'd like to be certain before starting using DFP. Could someone confirm please?
Then, sometimes I m using external html pages that I still load using Ajax. Should I consider writing the advertising banners JavaScript inside these external views, or directly inside the master page of my app?
Last question: How can I manage users having an adblocker software installed? Am I allowed to detect the presence of an adblocker software using JavaScript and then execute some specific code for this kind of users?
I'm working in a SPA and working with DFP successfully. Here is my feedback to your questions:
So I assume it's ok. But I'd like to be certain before starting using
DFP. Could someone confirm please?
Yes, you can refresh the banners using the method you are refering in the link you shared
Then, sometimes I m using external html pages that I still load using
Ajax. Should I consider writing the advertising banners JavaScript
inside these external views, or directly inside the master page of my
app?
To load them externally will bring you to lower performance results. You can control everything from the main page and you will have better results.
Last question: How can I manage users having an adblocker software
installed? Am I allowed to detect the presence of an adblocker
software using JavaScript and then execute some specific code for this
kind of users?
This is something I have not started to work on it but you can detect (like forbes.com is doing on it website) and there are also projects on dealing with this.
If I wanted to build a scraper that pings each URL on a site and stores the adobe (or Google) image request, how would I go about this? I.e. I just want something that grabs all the parameters in the URL posted to Adobe in a csv or something similar. I'm familiar with how to build simple web scrapers, but how do I grab the URL I see in for example Fiddler that contains all the variables being sent to the Analytics solution?
If I could do this I could run a script that lists all URLs with the corresponding tracking events that are being fired and it would make QAing much more manageable.
You should be able to query the DOM for the image object created by the tag request. I am more familiar with the IBM Digital Analytics (Coremetrics) platform and you can find the tag requests using accessing the following array document.cmTagCtl.cTI in the Web Console on a Coremetrics tagged page. I used this method when building a Selenium WebDriver test case and wanted to test for the analytics tags.
I don't have the equivalent for Adobe or GA at the moment since it depends in the library implementation am trying the do the same as you for GA.
Cheers,

Digging deeper into HttpHandlers I found they provide nice way to customize an ASP.NET application. I am new to ASP.NET and I want to know about different customizations that are possible using HttpHandlers. Lots of websites talk about how they are implemented but it would be nice to know some use cases beyond what ASP.NET already provides using HttpHandlers.
An ASPX page provides a base template (so to speak) for a form-based web page. By default, it outputs text/html and allows for easy adding of form elements and event handling for these elements.
In contrast, an HttpHandler is stripped to the bone. It is like a blank slate for HTTP requests. Therefore, an HttpHandler is good for many types of requests that do not necessarily require a web form. You could use an HttpHandler to output dynamic images, JSON, or many other MIME type results.
A couple examples:
1) You have a page which needs to make an AJAX call which will return a JSON response. An HttpHandler could be setup to handle this request and output the JSON.
2) You have a page which links to PDF documents that are stored as binary blobs in a database. An HttpHandler could be setup to handle this request and output the binary blob as a byte stream with a PDF MIME type for the content type.
Check this page for a good example and code of why you might want to customize them: http://dotnetslackers.com/articles/aspnet/Range-Specific-Requests-in-ASP-NET.aspx Essentially it can be used when you want to server certain files but not allow them to be accessible via a plain url (security).
I am building a website, within a large intranet, that wraps and adds functionality to another site within the same intranet. I do not have access to the other site's source and they do not provide any api's for the functionality they provide. I need to, somehow, have my server-side code go to that site, fill in some forms, then press a submit button.
Is this possible? If so, how can I accomplish this?
Note: I am working in asp.NET if that matters at all.
Not the most efficient, but maybe WatiN can get you started:
http://watin.sourceforge.net/
Just look at the URL the form is supposed to submit to and the method it employs (POST or GET) and then send a request to that URL using the same method and put the field you want as parameters
Your server-side code is basically a web client to the other web site. You will need to write the code to send the HTML form data to the other web site and process the response. I would start with the System.Net.WebClient class. Take a look at System.Net.WebClient.UploadValues. That class/method will enable you to POST the form data to the web site via a NameValueCollection.
