14.7.3 Content filter 411
If virusscan or the option "Verify content type" is enabled, the
content filter will modify requests to download only parts of a
file, so that always complete files are downloaded. In particular
some software updaters always expect partial content, even
though the reply indicates that the complete file is served. If you
encounter problems, please disable the named components for
the affected server.
If the component "Tag filter" or "Verify content type" is enabled,
requests will be modified to prevent automatic compression of
contents.
Virusscan
The status screens of the virusscanning module can cause problems with some
client software. Especially programs which automatically download files (e.g. to
update software components) can be affected. You can either disable the status
messages or the virusscan as a whole.
Tag filter
If the tag filter is active, some web sites can become unusable. Disable tag filtering
for problematic sites by adding them to the list without checking the tag filter
checkbox.
Content-Type
If this switch is not checked, both, "Verify content type" and "Content type filter",
are disabled for the given server.
Break SSL
For privacy reasons you might want to exclude some servers when breaking SSL
connections.
SSL checks
Define an exception if one of the SSL checks fails for a certain server.
14.7.3-B Virusscan
Do not scan documents of content type
In this control you can specify a list of content types. Corresponding documents will
not be scanned for viruses. To add an entry use the format "maintype/subtype", where
an asterisk (*) can be stated as the maintype or the subtype to match any value (e.g.
"image/*" for any image format). If the content type of a requested document is not in
this list, the file will be passed to the virusscanner before it is delivered to the client.
