刷新没有请求参数？ [英] refresh without request parameters?
问题描述
我有一个问题：我有一个带有一些按钮的表格。当按下其中一个
按钮时，一个新的URL带有一些参数，例如：从数据库中删除一些
。问题是，当用户按下刷新时，同样会再次使用参数来触发刷新URL - 这有时会给出
奇怪的行为。
重新加载页面以便只删除网页时，有什么办法可以规定参数吗？
http：//myserver/mypage.jsp？delete = yes
成为
http：//myserver/mypage.jsp
或者应该以其他方式处理吗？
问候

Hi,
I have a problem : I have a form with some buttons. When one of these
buttons is pressed a new URL with some parameters to e.g. delete something
from a database. The problem is that when the user presses refresh that same
URL is fired with the parameters to delete again - this sometimes gives
strange behaviour. Is there any way that I can stip of parameters when
reloading a page such that only the webpage is deleted e.g.
http://myserver/mypage.jsp?delete=yes
becomes
http://myserver/mypage.jsp
Or should this be handled some other way??
Regards
Bo

绝对。这正是他们发明GET和POST作为两种非常好的b $ b不同表单提交方法的原因。 GET方法，参数附加
到一个url，从数据库请求信息时很好，但是要修改那个数据库应该总是使用POST。拼出的网址是
加入书签，显示在推荐人日志中，一些蜘蛛解释GET表格，
....如果Googlebot每次抓取您的网页时会出现什么情况已从您的数据库中删除

Absolutely. This is exactly why they invented GET and POST as two very
different forms submission methods. The GET method, with parameters attched
to an url, is fine when requesting information from a database, but to
modify that database one should always use POST. Spelled out url''s are
bookmarked, show up in referrer logs, some spiders interpret GETted forms,
.... What if everytime the Googlebot crawled your page something was deleted
from your database?
