Re: [Pound Mailing List] multiple URLs configured on Pound not working

Hello Joe, 


    how many lines of URLs for OrURLs, or what is the limit of OrURLs?  Could it handle ~1000 lines?


Thanks, Q.Xie

Stage for upstream 2.7b now has an alternative method.

OrURLs
  URL "Url1"
  URL "Url2"
  ...
End

Patterns are combined into a single ((url1)|(url2)) string and compiled as one pattern.
