// CSI INCLUDE FOR HEADER AND FOOTER FILES
// JS file developed in support to convert all SSI Includes to a CSI Include using javascript
// javascript to read in two paramaters within the <div id="prim_sec">, based on the parameters, 
// the appropriate header file is loaded and then the appropriate secondary navigation link is 
// highlighted. If nothing is passed (no div exists), the header_main.htm is loaded by default.

// 082409: [bern} reduced header files to a single header.htm
//         no longer need ANY parameter for header.htm to load
//         added "none" case statement for pages that don't need a header
//         added interaction functionality for rebrand of header (pull-downs, language rollovers, bgiframe, sign in URI

// 090109: [bern] added if else statement to check if header already exists (hardcoded). 
//         if it doesn't exist, then it loads the header file.
//         if it does exist, then it applys the correct interaction by calling headerCallback();
//         hardcoding mainly done on outside vendor or application sites (forumns, OMS, investor, press, etc)
  
// 090309: [bern] 
//         ADDED THREE NEW FUNCTIONS
//           loadFooter() : load the footer when the <div "includeFooter">/csi/footer.htm</div> is in the page 
//           convertToAbsolute() : converts HF links, IMG src, FORM action, INPUT src to absolute URIs
//           convertToProxy() : prepends IMG src and INPUT src with /xilinx_HF for proxy servers
//         ADDED TWO NEW SWITCH CASES
//           absolute: used for sites like Registration and Search that can load the header using a relative link,
//                     but still need the links and images to be absolute
//           proxy: used for sites on DMZ like xapps that will use a proxy server to load the header, links need
//                  to be absolute and the images need /xilinx_HF prepended

// 091009: [bern]
//         updated convertToAbsolute(): IE6 adds the domain to the HREF so finding HREF's starting with "/" wasn't working
//            IE6 HREFs ended up being "http://testlinx" or whatever domain you were on


// 091409: [bern]
//         updated convertToProxy(): fixed IE security pop-up by converting IMG src to /xilinx_HF
//         first; moved changing URLs to absolute w/in function; added browser detection

// 111009: [bern]
//		   added language pulldown functionality - switching languages changes the domain, but keeps the same URL
//         added sign-in slide down panel
