The following VBScript function can be used in an ASP legacy application to extract the file name from a request.
public function GetFileName()
dim files, url, segments
url = Request.ServerVariables("path_info")
segments = split(url,"/")
url = segments(ubound(segments))
GetFileName = url
The function returns the last segment of the path information or URL. These are some examples:
||The default page in that directory(check web server settings)
This is useful when there is the need of an application rule associated to the file name. For example, a new rule may need to be created on your legacy application because robots are exploiting a security hole in your application. You may want to protect some pages that can be used to update information , and you want to add a security policy to only those pages. This function can be used to know the target page on the request and apply the security rule if the page has been configured to be protected.
I hope this is useful to someone.
