Where was the city of Ashdod?

Isaiah 20:1 (ESV)

1 In the year that the commander in chief, who was sent by Sargon the king of Assyria, came to Ashdod and fought against it and captured it

Ashdod was a Philistine city roughly halfway between Gaza and Joppa. Although it was part of the land given to the tribe of Judah (Joshua 15:47), it never actually came into their possession.
