How to use special characters in click links

Using ”#” (pound sign, number sign,%23 when URL encoded) in click-through URL’s, causes Internet Explorer and Safari 7, to strip everything after the ”#” character. Why?

The problem is browser specific for Internet Explorer, and occurs when a clickTAG is redirected via an ad server to the landing page. IE then strips the URL after the #-sign, causing the destination URL to be shorter than expected.

Replace the ”#” character, in the click-through URL, with %2523. This will fix the problem in Internet Explorer and still works in other browsers.

Using “|” (pipe) in click links when using image creative template, causes Cxense Display to parse the click URL wrong. How is that solved?

Use the HTML creative instead and use , and as shown below: Make sure the image creative is uploaded as a file, and use _P_ to reference to that image in the HTML creative.

<a target=_blank 
href="EASLink=http://www.seetickets.com/see/event.asp?e|artist=MARY+CHAPIN+CARPENTER
+AND+TIFT+MERRITT&n|artist=null&resultsperpage=20&filler1=see&filler2=art-
srch&orderby=date,time"><img src="_P_mcc-300x250-72dpi.gif" border="0" 
alt="EmediateAd" width="300" height="250"/></a>

Question 3

A Flash click-through URL containing %-encoded characters works in Firefox but gets un-encoded in Internet Explorer, causing different redirect URLs, only one of which is accepted by the site.

 Example:
clickTAG=http://www.site.dk/k%25F8b In Firefox this redirects to http://www.site.dk/k%F8b, which is an accepted URL on the site. In Internet Explorer this redirects to http://www.site.dk/køb, which is not an accepted URL on the site.

Answer:

You can “double-encode” the %-sign in the clickTAG as %2525. This will make both browsers redirect to the accepted URL on the site.
