[Logiweb] references

Sorry. Currently, restarting the server is the only way to repear 
inconsistencies between the server and the file system. Inconsistencies 
arise when

(1) Deleting, moving, or overwriting previous submissions.

(2) Looking up a page in the "advanced user interface" and clicking 
"delete".

Next version will have better ways to handle inconsistencies. 
Unfortunately, only the person who started the server can kill it and then 
restart it. All others must wait patiently until the server crashes (or 
send an e-mail to the owner of the server process).

I hope you mean {\lgwSomepageUrl} and not \{lgwSomepageUrl}.

\href{\lgwBaseUrl}{base} denotes \href applied first to \lgwBaseUrl and 
then base. The TeX manual states that spaces after a control sequence are
ignored so that \href{\lgwBaseUrl}{base} and \href {\lgwBaseUrl}{base} 
mean the same. A single newline counts as a space (two newlines count as 
a \par).

If you omit braces, a command just takes the next two characters as 
arguments so that \href abc means \href{a}{b}c.

If you write \href\{lgwBaseUrl}{base} then \{ is a command for producing 
a left brace so that \href\{lgwBaseUrl}{base} means
\href{\{}{l}gwBaseUrl}{base} which is likely to fool TeX.
