asp.net - Converting querystring to filename - best practise? -


i have handler (c#/asp.net) pulls images database. current format looks foo.com/_image.ashx?querystring1&querystring2 querystring keys things id, width, zoom level etc.

i can either munge filename (i.e. foo.com/id__999_w__128__h__200.jpg), or whole url structure (i.e. foo.com/id/999/w/128/h/200/image.jpg).

im interested see other people given situation, there dont seem articles or discussions of practice on net.

the easiest solution base64 filename, can pretty guarantee filename correct each time, , not tampered or broken.

string filename = @"c:\images\myimage.png";  // may need change encoding type here string converted = convert.tobase64string(     system.text.encoding.default.getbytes(filename));
