Add text to output_buffer for later printing. Used
hputs ?-error? text
The mod_dtcl version of "puts". Outputs to the
client, instead of to stdout.
The error option permits you to send an 'error message' to the
apache log file, at the NOTICE level.
var These commands retrieve or
retrieve information about "CGI" variables that are passed to
the dtcl script via GET or POST operations.
var get varname Returns the
value of variable 'varname' as a string (even if there are
var list varname
Returns the value of variable 'varname' as a list, if there
are multiple values.
var exists varname
Returns 1 if varname exists, 0 if it doesn't.
Returns the number of variables.
Return a list of variable names and values.
upload These commands retrieve or
retrieve information about files that have been uploaded to
the server. They replace the UPLOAD variable.
upload get varname channel
Returns a Tcl channel that can be used to access the uploaded file.
upload get varname save name
Moves the uploaded file to the give name.
upload get varname data
Returns data uploaded to the server. This is binary clean.
upload info varname exists
Returns 1 if the variable exists, 0 if not.
upload info varname size

upload info varname filename
Returns the filename on the remote host that uploaded the file.
upload names Returns the variable
names, as a list, of all the files uploaded.
hgetvars Get environmental, and Cookie
variables. This is in a separate command so as not to make the
server do this every time you load a .ttml file. ENVS, CLIENT_ENVS and
COOKIES are the associative arrays created. ENVS contains
environmental variables. CLIENT_ENVS contains the headers received from the client.
COOKIES contains any cookies
received from the client.
Include a file without parsing it. This is the best
way to include an HTML file or any other static content.
"Source" a .ttml file. This is the way to include
other .ttml files.
Flush the output buffers to the client. Use this if
you want to incrementally update a page.
headers redirect uri
Redirect from the current page to a new
URI. Must be done in the first block of TCL code.
headers setcookie -name cookie-name
-value cookie-value ?-expires date/time? ?-domain domain?
?-path path? ?-secure?
This command is for setting cookies. Cookie-name is
the name of the cookie, cookie-value is the data
associated with the variable. Expires sets an
expiration date for the cookie, and must be in the
format 'DD-Mon-YY HH:MM:SS', path sets the path for
which the cookie is valid, and secure specifies that
the cookie is only to be transmitted if the connection
is secure (HTTPS).
This command sets the "Content-type:" header returned
by the script, which is useful if you wish to create a
PNG (image), for example, with mod_dtcl.
headers set headername value
Set arbitrary header names and values.
Create a self referencing URL from a filename. For example:
makeurl /tclp.gif returns
Prints information on the internals of the module in
