http request haproxy cut string

I have a question about a http request in haproxy. I have the following problem.

i have a variable url e.g.

http://mywebsite.com/job/1/hello-world/display/redirect

Everything between http://mywebsite.com/ and

/display/redirect

can be variable. Now I want everything that goes to ...../display/redirect to be cut off so that goes to http://mywebsite.com/job/1/hello-world without /display/redirect there is a way to define that ? I have the possibility to define fixed urls but how is that with variable urls where only the end is always according to the principle ?

I've been thinking about something like :

http-request redirect code 301 location http://mywebsite.com/ [..] if {path_beg [..]/display/redirect}
