This may seem like a pretty easy question but I would like to ask what does this condition says?

VB

if instr(LCase(Request.ServerVariables("HTTP_HOST")),"corpwebdev") > 0 or instr(LCase(Request.ServerVariables("HTTP_HOST")),"_train") > 0 then
        cnOracle.Open "PROVIDER=MSDAORA;DATA SOURCE=TestDB;USER ID=DBuser;PASSWORD=DBuser"
    else
        cnOracle.Open "PROVIDER=MSDAORA;DATA SOURCE=ProdDB;USER ID=DBuser;PASSWORD=DBuser"
    end if

The one that tricks me is the "if instr(LCase(Request.ServerVariables("HTTP_HOST")),"stluscorpwebdev") > 0 or instr(LCase(Request.ServerVariables("HTTP_HOST")),"_train") > 0" part.

Thank you in advance!

If you google HTTP_HOST you'll see that it stores "the Internet host and port number of the resource being requested." http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.23[^]

This code uses a different connection string (to a test vs production db it appears) depending on which server the code is running on.

Thank you Ryan! We just migrated server, do I need to change the host? Can you help me go to the direction wherein I can find the internethost and port number ? Again, thank you so much!

If the code works you can leave it alone otherwise, ya, you'll need to change it.

The internet host is what you type in to get to it. For example: www.microsoft.com is the host.

Thanks again but unfortunately I need to make necessary changes because if not, it will fall to else condition which is our production database instead of development database. Now we don't want that hehe. Appreciate your help, I'll just do necessary changes.

Yes, be very careful which db you are accessing. ;)
