Thanks itpp2012
I was actually just experimenting with that approach! I was beginning to have a bit of success too! Not quite there yet though.
map $uri $site_folder {
#~^/(?P<folder>[a-zA-Z]+)/.* $folder;
~^/(?P<folder>[a-z]+)/.* $folder;
}
I saw an example very similar(or same) as what you gave me on a wordpress multi site page.
I think my regex is a bit messed up but I will keep on going down this route. Looks very promising!!!
** I think my pcre is old, as I have to use the ?P syntax.
At one point, I was able to capture the folder name into the variable but ONLY if there was no characters after the slash (domain.com/site1/)
Thanks again! (to everyone)
