HTTP Proxy Server and Regex Matching

[Ryszard Lach <si...@autograf.pl>]

Hi.
According to documentation when http proxy server finds in response a
string which matches value of UDV it is replaced in testing profile by a
name of this variable, right?

I think, that more useful would be if one could define a variable, which
would substitute a string with a pair like 'string=${variable}', e.g.
like that:

if you find string matching id_user=(\w+), then replace it with
id_user=${username}

Is something like that possible?

I don't see how this can be done with the existing variable definition
test elements.

How about adding a "Replacement Pattern" section to the Proxy server?
For example:

Match RE                         Replacement
id_user=\d+                     id_user=${id}
pair=\(\d+,\d+)                 pair=(${a},${b})

The Match string would be assumed to be a Regular Expression.

Would this meet your needs?

Maybe another configuration element or part of http proxy server, similar to 
User Defined Variables with columns:

"pattern"	->	"referencing variable"

e.g.

id_user=(\d+)	->	id

resulting in replacement

id_user=${id}				

I was trying to use UDV for that entering regexp as value. Maybe a checkbox 
telling "use value as pattern" would be enough? When checked it could cause 
replacing match with variable's name; this of course would require defining 
the variable once more with this checkbox unchecked (to replace the variable 
with value during test plan execution).

Sounds like a useful enhancement - but I'm not clear how would you
tell JMeter how to find the text.

Do you have any suggestions for the changes to the UI?
