why to use double &&

[marknav]

I transfer parameters with:
file.cfm?param=value1&param2=value2
However i noitced an example written this way:
file.cfm?param=value1&&param2=value2

Why to use double && ?

Thank you

It shouldn't make a difference -- either is correct, in my opinion. The second example just makes a longer URL with no benefit that I can think of.

Does anyone know a reason why a specific web server would treat these examples differently?

Was the example on a webpage (ie - written in HTML)?

It may have been that the author got a little tripped up in how to escape an ampersand.

I can't think of any reason to use

&&

. Single ampersands are what I've always used, and they have never failed me

I know

&&

used to mean "concatenate two strings with a space inserted between them" in some programming languages. But that doesn't seem particularly useful in this instance. Hope it helps,
