Keywords: The web cache has done it before, through OWC, dynamically display the chart on the web page. The implementation method is based on the passing parameters, which is turned OWC, generated a picture (MyGIF.GIF), and then dynamically be on HTML.
Label ???
Then output to the client. Displayed on the web. But the problem is coming, although mygif.gif. It has been regenerated, which may display the style from the histogram into a graph, and the display content has become data from January to data. But the image on the re-output web page is still an old picture, although the picture has been overwritten on the server. This is actually a picture of the IE cache. IE is only detected
The label SRC has not changed to take the cache to Mygif.gif to display, I don't know the server's MyGIF.gif has been updated??? How to make IE do not display cache content? Just tell IE, SRC is changed, IE will get a new display image or resource from the server from the server according to the new SRC. ??? So I output to the client on the server.
The following changes are made as follows.
SRC = mygif.gif? = [unique code]
Supplement: I don't know what is going on, becoming garbled, now I use the key place to mark it.
