4.5.9 iRule URI redirect question

I have been tasked with creating a common VS where all incoming requests would be redirected to a common landing page. My question is does the 4.5.9 rules have a limitation on size (how big it is) or on character limit. We're talking 20 to 30 redirects here. For example:

 

 

http://companya/abc is redirected to http://companyb/abc

 

http://companya/def is redirected to http://companyb/abc

 

maybe 20 more after these 2.

 

 

 

Thanks,
