Different code in "headinclude" template

[محروم.كوم]

<div>Just wondering if there is a conditional that can be used to have different code in the headinclude template depending on whether a user is browsing the main page (ie www.thesite.com) or any one of the other pages (ie www.thesite.com/forum/showthread....).

I've found some PHP conditionals but unfortunately this is not supported in a template.

<div class="bbcode_container"> PHP Code:

<span style="color: #000000"> <span style="color: #0000BB"> __DEFINE_LIKE_SHARE__
