What is the meaning of a ^ sign in a URL?
I needed to crawl some link data from a webpage and I was using a simple handwritten PHP crawler for it. The crawler usually works fine; then I came to a URL like this:
http://www.example.com/example.asp?x7=3^^^^^select%20col1,col2%20from%20table%20where%20recordid%3E=20^^^^^
This URL works fine when typed in a browser but my crawler is not able to retrieve this page. I am getting an "HTTP request failed error".

In a URL, a hash mark, number sign, or pound sign ( # ) points a browser to a specific spot in a page or website. It is used to separate the URI of an object from a fragment identifier.
So in your case, the first part of the URL is a request to the server: http://dev.ibiza.jp:3000/facebook/report? advertiser_id=2102. and the second part of the URL could be for Javascript to display a specific view of the page once it has loaded: #/dashboard.
Percent-encoding is a mechanism to encode 8-bit characters that have specific meaning in the context of URLs. It is sometimes called URL encoding. The encoding consists of substitution: A '%' followed by the hexadecimal representation of the ASCII value of the replace character.
A space is assigned number 32, which is 20 in hexadecimal. When you see “%20,” it represents a space in an encoded URL, for example, http://www.example.com/products%20and%20services.html.
^ characters should be encoded, see RFC 1738 Uniform Resource Locators (URL):
Other characters are unsafe because gateways and other transport agents are known to sometimes modify such characters. These characters are "{", "}", "|", "\", "^", "~", "[", "]", and "`".
All unsafe characters must always be encoded within a URL
You could try URL encoding the ^ character.

Based on the context, I'd guess they're a homespun attempt to URL-encode quote-marks.
