This has been a real FAQ now! I solved this problem in a different way
and have post it before. I do not quite understand the \IfFileExist
thing and I was using the following way just fine. (It modify the lyx
file and convert \url to \htmladdnormallink.)

Before lyx1.2.1 fix the problem of getting proper links out of lyx
generated latex file by latex2html, I am using a perl script to
translate lyx URLs to corresponding ERTs as a temporary solution.
1. put the following to your preamble:
\usepackage{html}
\usepackage{url}
\latex{\renewcommand{\htmladdnormallink}[2]{#1 (\url{#2})}}
as suggest by lyx.org tricks->URLs.
2. Use usual insert URL. (The lyx file will be like \begin_inset
LatexComm�nd \url ....)
3. Save the lyx file and run the following command
perl -pe 's/\\begin_inset LatexCommand \\url\[(.*)\]\{(.*)\}/\\begin_inset
+ERT\nstatus Collapsed\n\n\\layout
+Standard\n\n\n\\backslash\nhtmladdnormallink\{$1\}\{$2\}\n/gs' old.lyx > new.lyx
This basically translate "\begin_inset LatexCommand ..." to "\begin_inset
ERT \htmladdnormallink ..." You can open new.lyx to see what is
happening.
4. convert new.lyx to new.tex with lyx -export latex new.lyx
and then latex2html new.tex.
This procedure can be automated by make:
$(TEXFILE): $(LYXFILE)
rm -f /tmp/a.lyx
perl -pe 's/\\begin_inset LatexCommand
+\\url\[(.*)\]\{(.*)\}/\\begin_inset ERT\nstatus Collapsed\n\n\\layout
+Standard\n\n\n\\backslash\nhtmladdnormallink\{$$1\}\{$$2\}\n/gs' ${LYXFILE} >
+/tmp/a.lyx
lyx --export latex /tmp/a.lyx
mv /tmp/a.tex $(TEXFILE)
Note that $$1 will be translated into $1 by make.
Or be incorporated into lyx by a perl script.
