I need to accept a list of file names in a query string. ie:
http://someSite/someApp/myUtil.ashx?files=file1.txt|file2.bmp|file3.doc Do you have any recommendations on what delimiter to use?
If they’re filenames, a good choice would be a character which is disallowed in filenames. Suggestions so far included
, | &which are generally allowed in filenames and therefore might lead to ambiguities./on the other hand is generally not allowed, not even on Windows. It is allowed in URIs, and it has no special meaning in query strings.Example:
http://someSite/someApp/myUtil.ashx?files=file1.txt|file2.bmp|file3.docis bad because it may refer to the valid filefile1.txt|file2.bmp.http://someSite/someApp/myUtil.ashx?files=file1.txt/file2.bmp/file3.docunambiguously refers to 3 files.
