Question

I need to exclude some URLs for a jMeter test:

dont exclude:

http://foo/bar/is/valid/with/this
http://foo/bar/is/also/valid/with/that

exclude:

http://foo/bar/is/not/valid/with/?=action
http://foo/bar/is/not/valid/with/?=action
http://foo/bar/is/not/valid/with/specialword

Please help me?

My following Regex isnt working:

foo/(\?=|\?action|\?form_action|specialword).*

Answer 1

First problem: / is the general delimiter so escape it with \/ or alter the delimiter.
Second Problem: It will match only foo/action and so on, you need to include a wildcard before the brackets: foo\/.*(\?=|\?action|\?form_action|specialword).*

So:

/foo\/.*(\?=|\?action|\?form_action|specialword).*/

Next problem is that this will match the opposite: Your excludes. You can either finetune your regex to do the inverse OR you can handle this in your language (i.e. if there is no match, do this and that).

Always pay attention to special characters in regex. See here also.
