|Writes a string to the log
string - The method converts this to a string and
writes it to the log file.
<% Response.AppendToLog("My variable X=" + X) %>
<% Response.AppendToLog "My variable X=" & X %>
ALP automatically creates or appends the log file when this method
is used. The log file is named alplog.txt and is created in
the root of the Virtual ALP site. No errors are reported if the file
cannot be created (for example on read-only media). Note that you
should remove/comment all the unneeded AppendToLog calls in the retail
version of the application in order to prevent creation of huge log
files no one would want to use.
When to use? In many cases it is more convenient to use
Response.Write to output trace information from the ASP pages.
However, the design of some pages may cause problems for such an
approach (for example the output may fall in a select box). In such
cases you would want to separate the trace information from the
regular page output and the AppendToLog method will help you do that.
If you want to clear the log file automatically you can do this in
the global.asa - for example in the Application_OnStart function. To
do so you will need to use SFMain
object to delete the exiting log file.
