here's another obvious question:

if you're in a servlet, and you're getting an & separated string from
somewhere, where is the "somewhere" that you're getting it from?

does the servlet activate and collection the data somehow, or does the
data get sent to the servlet (in, for example the query string)?
The data is sent via an HTTP POST request, with the query string lightly encrypted.

From: David Kerber [mailto:[EMAIL PROTECTED] Is there a more efficient "split" method I could use? Or am I completely missing the point of what you are suggesting?
I think you've slightly missed the point.  I assume you're calling your 
function 5 times, each with a different field name that you want out of it.  
You're then invoking string handling functions on the entire decrypted string 5 
times, each time going through the bytes to extract the piece you need.  In the 
process, you traverse bytes you don't need several times.  My suggestion is 
that you tokenise this *once*, and hence only pay the string-handling overhead 
once.  Then you get all the parameters out of the same tokenised version.

However, if the next thing you do is to write this to disk, I am even more 
convinced that you're optimising the wrong piece of code as the disk I/O is 
likely to take vastly more instructions than the string parse.

These may be naïve questions, but I'll ask them anyway.  How have you 
identified these two pieces of code as the targets for optimisation?  What 
profiler have you used, under what conditions?  What proportion of your overall 
CPU budget is taken by these two snippets of code?  Is the machine CPU-bound in 
the first place, or is the bottleneck elsewhere?  If these are the worst 
culprits in your app, I'll be very surprised.
