More URI-Related UDFs

To follow up my parseUri() function, here are several more UDFs I've written recently to help with URI management:

  • getPageUri()
    Returns a struct containing the relative and absolute URIs of the current page. The difference between getPageUri().relative and CGI.SCRIPT_NAME is that the former will include the query string, if present.
  • matchUri(testUri, [masterUri])
    Returns a Boolean indicating whether or not two URIs are the same, disregarding the following differences:
    • Fragments (page anchors), e.g., "#top".
    • Inclusion of "index.cfm" in paths, e.g., "/dir/" vs. "/dir/index.cfm" (supports trailing query strings).
    If masterUri is not provided, the current page is used for comparison (supports both relative and absolute URIs).
  • replaceUriQueryKey(uri, key, substring)
    Replaces a URI query key and its value with a supplied key=value pair. Works with relative and absolute URIs, as well as standalone query strings (with or without a leading "?"). This is also used to support the following two UDFs:
  • addUriQueryKey(uri, key, value)
    Removes any existing instances of the supplied key, then appends it together with the provided value to the provided URI.
  • removeUriQueryKey(uri, key)
    Removes one or more query keys (comma delimited) and their values from the provided URI.

Now that I have these at my disposal, I frequently find myself using them in combination with each other. E.g.:

<a href="<cfoutput>#addUriQueryKey(

Let me know if you find any of these useful.

In other news, this cracked me up.
