prefixurl(base='')

source code 

Sorry, this function is really difficult to explain. Maybe some other time.

expires(delta)

source code 

Outputs an `Expires` header for `delta` from now. `delta` is a `timedelta` object or a number of seconds.

modified(date=None, etag=None)

source code 

Checks to see if the page has been modified since the version in the requester's cache.

When you publish pages, you can include `Last-Modified` and `ETag` with the date the page was last modified and an opaque token for the particular version, respectively. When readers reload the page, the browser sends along the modification date and etag value for the version it has in its cache. If the page hasn't changed, the server can just return `304 Not Modified` and not have to send the whole page again.

This function takes the last-modified date `date` and the ETag `etag` and checks the headers to see if they match. If they do, it returns `True`, or otherwise it raises NotModified error. It also sets `Last-Modified` and `ETag` output headers.

urlencode(query, doseq=0)

source code 

Same as urllib.urlencode, but supports unicode strings.

>>> urlencode({'text':'foo bar'})
'text=foo+bar'
>>> urlencode({'x': [1, 2]}, doseq=True)
'x=1&x=2'

changequery(query=None, **kw)

source code 

Imagine you're at `/foo?a=1&b=2`. Then `changequery(a=3)` will return `/foo?a=3&b=2` -- the same URL but with the arguments you requested changed.
