New Revision: 7587
URL: http://svn.digium.com/view/asterisk?rev=7587&view=rev
Log:
- construct the difference and have only one call to snprintf in build_via
- convert some while loops to for loops
- localize some variables and remove unneeded initializations
- store result of get_header locally so it only has to be called once
- remove some duplicate calls to strcasecmp by storing result
(issue #5955)
